Sure. But as you see, at least Joshua D. Drake is quite happy with

patch -p1 < all_his_replicator_changes.diff

I'm, too. Because I don't think I could get anything useful into core.
And as long as I'd still have to patch the backend, what would that
serve me?

I really think this decision should be left to the developers of
replication systems. We *will* ask core, if we want to have something
added (as did the GORDA project). I state the same in my FAQ at [1].

Okay, sorry, then I misread you.

Have they? Have you heard requests for specific additions into core from
any of them?

Sure.
