A decade into the 21st century people are still making wet plate images, ambrotype prints, home-made emulsions etc, using 19th C cameras, pre-WWWII cameras and lenses yet you don't jump down their throats.
Matt has converted his Graphic front standard, is that turning a silk purse into a pigs ear, the truth is the other way around it's giving him greater functionality, and practical flexibility from a camera that despite being designed & made in the 20th C lacks features that UK and continental equivalents already had in the late 19th C.
Speed & Crown Graphics have become very over priced & over hyped recently to the extent that they can sometimes fetch more than a reasonable field camera, but if someone's lucky to get one for a reasonable price then why not make these changes. Personally I wouldn't make irreversible changes hence converting a spare front standard, but it's extraordinarily simple to do, for a huge gain in usability.
