Well, you answer that question in your own suggestion:

I don't know anything about zargs but it would seem that with a large
recursive filename glob expansion that overflowing ARG_MAX is a more
likely possibility.  Using find avoids that problem completely.

It also follows the unix philosophy of small modular programs.  Having
learned that grep provides the --include option you have learned only
that grep provides the --include option.  That won't help you with
awk, sed, chmod, ls, etc.  But having learned to use find you can now
use it with other commands in a general way.
