The solution to the carpentry problem is metric building materials.
Instead of 16” centers, you do 400mm centers and your metric drywall is 1200mm wide. Voila.
Your 2x4’s aren’t 2” x 4” anyway.
The NIBS “Construction Metrication” newsletter mentioned this kind of problem - people trying to figure out how to fit 1219.2mm drywall on 406.4mm centers. Ridiculous.
Here’s the NIBS publications on the subject: https://www.nibs.org/index.php/nibs/resources/constructionmetrication
I see all that stuff was published in the 90s, and it hasn't caught on in the intervening years, certainly not around here. I'm a charter subscriber to Fine Homebuilding, which is one of the best design/build magazines around and despite their expertise rather 'green' and 'touchy feely' countercultural, and THEY don't mention it, which means it hasn't caught on even with the true believers.
The "nominal" dimensioned framing lumber has been around for years, we've all learned to deal with it - since it's slightly smaller than true dimension it doesn't really cause a problem in framing. If you have to stack or sister on near a wall you do have to measure (but you should be measuring anyway!)
Where the problems REALLY get interesting is when you're working on an old house (pre-WWI) and find that you have to integrate nominal dimension framing with the old "true" dimension stuff. That will give you gray hair (if you don't tear it out first). Also, if you're using hardwoods the nominal dimensions are different, but that's for finish carpenters who are a breed apart from us "rough carpenters" -- i.e. 'good on rough work, and rough on good work.'
