This is somewhat radical and might surprise people.  And it might be a
good idea if previous non-interactive calls kept their API (which
basically means clever use of &optional or similar).

How about making a configurable "grep-find-prompt" option that is a
list or string with possible elements "p" and "c".  The old default
would be "c" (prompting with command), the new default "p" (prompting
for parts), and an interactive argument would temporarily give "pc",
where the parts are queried first, and then the finished command is
offered again with point at a convenient location for adding `find'

Something like that.  That way, people can easily reconfigure the old
behavior if they want to.  And use C-u M-x grep-find RET for being
able to post-edit the command, and maybe C-u C-u M-x grep-find RET for
getting the inverse than the default behavior.
