Yes, because some people want to set specific programs. If you have code
which checks for things at the point of being called, this becomes more
complicated than necessary. If on the other hand you just check when
first initialising, users who want to can override with a simple setq.
It is also more efficient as the check is only done once at load time
rather than every time you export to pdf.

It should also be noted that the custom framework has good support for
doing it this way. You can even add code which will check values entered
by the user to verify they exist (for example and assuming they use
custom to set a new value and not just a setq in their init file).
