Time for me to chime in, I guess.

As a long-time Perforce unenthusiast, I'm glad to see people working on
this sort of thing. However. including stuff in the tree is effectively
a promise to support it, so we've got to think pretty seriously about it
when it's non-trivial.

Right now it has the following upsides:

- you're enthusiastic about it
- it helps Perforce users find it
- it'll help you keep in sync with us

And downsides:

- being in tree will slow down your still-early development
- you're about the only person around who's got Perforce expertise
- there isn't much in the way of a visible user base
- we've got a few other hybrids to consider and whether/how to manage
their consistency

On balance, I think the answer is not a definite "no", but is at least a
"too soon".
