This would eliminate most wallet-related protocols e.g. BIP69 (sorted
keys), ypubs, zpubs, etc. I don't particularly like any of those but if
they can't be BIPs then they'd need to find another spec repository
where they wouldn't be lost and where updates could be tracked.

The SLIP repo could serve this purpose, and I think e.g. SLIP39 is not a BIP
in part because of perceived friction and exclusivity of the BIPs repo.
But I'm not thrilled with this situation.

In fact, I would prefer that OpenTimestamps were a BIP :).

Well, LN is a bit special because it's so big that it can have its own
spec repo which is actively maintained and used.

While it's technically true that BIPs need "approval of Core maintainers" 
to be merged, the text of BIP2 suggests that this approval should be a
functionary role and be pretty-much automatic. And not require the BIP
be relevant or interesting or desireable to Core developers.
