There's one I can think of: SLY, because there external tool's
completion code can be tweaked to fit the needs of Emacs :-)

For most others it's probably difficult, indeed, which is why
I suggested to make it optional (unless you know how the tool
does its matching in which case you may be able to re-use
`completion-pcm--merge-try` or to implement something similar).

The default UI uses either tryc (when you hit TAB) or allc (when you
ask the see *Completions*) not both.
