This is not strictly necessary to set them before the whole Org is
loaded. In some cases, only part of Org has to be reloaded: font-locking
setup; parser; folding state; etc (which is a normal scenario when done
interactively). However, such reloading adds up to file opening time. It
is much faster to set everything once and load Org compared to (1) load
org; (2) load variable and reload org; (3) load another variable and
reload org; and so on.

+ creating a dedicated minor mode for every variable is not maintainable.

Having Emacs support early setting would be much easier.

Best,
Ihor
