Why are you assuming that any 'find' job would necessarily use -exec?

Did you ever need to customize this variable, on any system?  Because
if you didn't, I'm not sure you will ever be able to understand the
need.  Users of GNU/Linux will never need to use this variable.

But since you asked: you might have 2 versions of 'find' (under
different names), one that is good at invoking programs via -exec, the
other that supports the -print0 action.

Basically, imagine a system with several different ports of 'find',
each port with its own advantages and bugs.
