Even if it could be implemented quickly (and I won't be able to do so), it's way too late and intrusive for the 19.x release. Maybe one of the other reviewers could chime in?

That's a fair point, I think it's too late to make such a large change for the 19.x release so I'm fine merging this change despite the potential performance regression (although that's a pre-existing issue), but I think we should file an issue to implement the proper solution after.
