People got pulled from class for vacations all the time when I was a kid.
It wasn't super common, but it was common enough that there was a standard procedure around it (basically you'd get the classwork/homework that you'd be missing and be expected to present it upon return).
I think a bigger part now is that schools are somewhat more overloaded, so missing class puts you "out of sync" and there's nothing to help you catch back up. When I was young the parents were expected to do that: I don't know how common it is now.
There’s a serious “butts in seats = cash” focus from admin, now. I’m not sure if funding arrangements used (80s and 90s? Pre-nclb? I dunno) to be different.
