Have you considered disabling creating the fallback textures for

No, I hadn't. Given that nobody ever intentionally executes with a
fallback texture, do we care to reduce its overhead?
FWIW, years ago there was a GL screensaver program that rendered with an
incomplete texture state and relied on correctly handling of that to
produce the right image. That would hit the fallback texture code.
I notified the author of the program about the issue back then. In any
case, I wouldn't worry about it.
