-maxdepth necessarily, but the way find-dired is structured makes it
impossible to reuse any of the code to write a command that could support

I made a mistake in my initial analysis. find (at least the version I have)
allows one to pass global options such as -maxdepth like so:

    find . \( -maxdepth 3 ARGS \) -ls

However, find will print a warning message as this usage is not recommended.

Also, I realized that my previous patch, while functional, is awkward since
it exists solely to allow users to specify global options
(based on the discussion on #27456, I believe all other find functionality
should be possible with find-dired).
I have made a new patch adding an optional parameter to find-dired for
passing such global options to find.

Aside: there is a discussion at #32668 about adding a similar command line
editing feature like rgrep
I'm not fond of that as it is impossible to use programmatically and
interacts poorly (read: not at all)
with `repeat-complex-command'
