I expect the need for consultation with retired engineers relates to understanding of how the manufacturing challenges were solved in the past.
If plans were initially designed with those legacy manufacturing techniques and tools and equipment and skilled technicians in mind, then there may very well be a need to have the retired engineers explain those contextual assumptions to the newer engineers.
I expect that there may have been a lot of "why did they do this this way?" conversations.
The older plans may also have referenced sub-assemblies that were then available from third parties, but are no longer made.
Sort of like modern automotive engineers having to have carburetors and manual chokes explained for them.
I am wondering if the people complaining about the format ever used a half-frame?
Also, many 645 are in "phone orientation".
Are they? All of the dedicated 645 cameras that I know from Pentax, Contax, Hasselblad, and Mamiya are horizontal orientation.
Maybe the 6x4.5cm backs for 6x6cm, 6x7cm, or 6x9cm cameras are in vertical orientation.
It just doesn't seem like the right choice for the return to film cameras by Pentax, who are most known for their 35mm and medium format SLR cameras.
I've always thought it interesting that Pentax never got into any of the "alternative-to-35mm" formats, such as half-frame, APS, Disc, 110, 16mm, etc. Nearly everybody else did (including their current owner, Ricoh) -- of course some were big, costly flops! But NOW, they see an opening. Maybe it's Ricoh that's leading the way -- which has a rich history in half-frame:
It took Kodak over a hundred years to finally market a half-frame 35mm camera. Why should Pentax be any different???
Everything I know about Japanese business culture could probably be printed on a postage stamp but with that limited understanding, I suspect that the message Ricoh/Pentax are trying to make has little to do with the skills of the current engineering staff. When they say, "...our current staff couldn't understand so, we invited some retired/older engineers in to collaborate with our current staff", etc... I suspect they are trying to make a statement regarding honoring the past, honoring the wise men who came before us, approaching this with humility, not being so arrogant as to start from scratch, etc...
Honor and a connection to the past ... It may be as simple as that.

Unused engineering knowledge that has been superseded becomes lost very quickly.
Not to go off track too much, but I often fear this concerning film emulsion manufacturing, coating, and colour lab equipment and scanning.
Consider what sticking to that strategy got Pentax into. Pentax was sold to Ricoh for (slight exaggeration there) what Leica now charges for their new M6.
Leica has also non-rangefinders, e.g. a few compacts. So a half-frame or 35mm compact would not mean Pentax/Ricoh is not an SLR-centered company...like Leica is the rangefinder company, Pentax could be the SLR company.

I don't think that Leica's business model would be a good fit for Pentax, unless Pentax can thrive on sales of ~5000 film cameras per year.
There's likely nothing wrong with the quality of engineers at Pentax/Ricoh. But they won't be used to working with 2D physical blueprints or complex, tiny mechanical machines. In the same way not a single one of the old cassette deck manufacturers can make one now. In the same way Sankyo abandoned making a new super 8 camera in the early 00's despite having a stash of spare parts and the blueprints for their 60s and 70s models. The knowledge has been lost, and even where blueprints exist and a physical example exists to be reverse engineered....it's too complex to bother with. There are lots of things humans could do in the past that we cannot feasibly do now.....Egyptian pyramids, Rapa Nue Moai, Stonehenge. We think we've finally figured out how the Moai were transported after hundreds of years thinking about it.

When this camera comes out, there should be a ticker-tape parade!
