Why can't it still crack the flush plaster you put over the tape?

The paper if flexible enough to give.

Surely gypsum board is in use throughout the world; can't be only US.

in the UK anyway plasterboard sheets have to different sides used
for different applications.....

Well there are two sides here, too...the back side and the finish side.

There's no purpose for putting the wrong side out.

For what???

Never seen back side out installation for any purpose.

If you are going to give the whole wall a 3mm skim of gypsum
multi-finish plaster, then you normally use square edge boards
backside out.

Few big builders bother with a skim, they just tape and seal the
tapered-edge and use a special filler on the joint then just
decorate.
