What Happens When We Ultra-Dilute Pyrocat-HDC?

If it's there (streaking) it will be close to the sprocket holes for sure. I think the power line shot

The only "unevenness" I see is in the 3rd example behind the tower on the left side. But this could have actually been the lighting or a scanning artefact. I have to check

and the woods scene look like a 35mm shot trying to be a "Big Boy" medium format shot. Those last two look to have the quality of medium format. Of course we're not looking at a 16X20" print. Still, those are darn nice to look at.

Yes, the ultra sharp, widely separated middle tones really make 35mm look the big boys.
 

I agree, if it were really a case of bromide drag you'd see it all the way across the top and on most every sprocket hole. Combined this developer and dilution with a good lens and a film like Tmax 100 and it could almost (?) come close to 4X5. Got to try this with my Contax G1 and its 45mm f2 Planar since my main developer is Pyrocat-HDC anyway.
 

Just be generous with total developer volume and put the reel on an inverted funnel.

....and show us the results

I'll treat it like I do Perceptol 1+3. When I use Perceptol 1+3 I use a two reel SS tank for 120/220 film with an empty 35mm reel on the bottom of the tank and the next reel with the film. I've also become gentler with all my agitation than I used to be. I'm going to develop some film that way tomorrow and will post result of that and some Adox HR-50 film tests I did earlier. Oh, and it won't be super scientific either!
