It's kind of implicit in the Change proposal. When you submit a
Change, you are indicating that you want this to be something that
Fedora promotes (both from an engineering standpoint and a marketing one).

With something like Ganesha, in part because there are other network
filesystem implementations that are well-known, it's fairly easily
understood that this is an additive change.

However, with remote journal logging, there currently exists no
mechanism for this (except for dumping syslog, which loses all of the
enhanced capabilities of journald)

That would make this much more palatable, thank you.

This was an impression I got from the discussion thread up to that
point. I didn't get a sense that the core journald developers were in
agreement with this as the approach (and as noted above, it appeared
that this was being pushed as the One True Way to do this).

Right, as noted above we should be clear about this when we talk about it.

So the obvious question here is whether we should accept this as a
Change now. Given that you are contemplating a significant protocol
modification, would it make more sense to defer this Change until F22?
(that doesn't mean you can't have the code in Fedora, just that we
won't market it and push people towards testing it in F21).
