No.  Only the most primitive calls of find-grep can be catered for by
"grep's" -r and --include options, and many greps don't even have
those options.

Which is why we are discussing how to merge them...

Disagree.  Find can't be obliterated for all usage cases, but using it
for something like *.[ch] would certainly be inconvenient.

The setting of case-fold-search rarely is fine-tuned to the current
editing need, so I doubt that passing it on to grep would feel natural
to people.
