FTR, I'd have preferred for the line numbers to be considered outside of
the window edge, together with fringes and margins. And I still don't
see any downside to it (except it might be harder to implement).
As it is now, third-party code has to adapt instead, by handling the
line numbers specially.

Not sure. What about them? We don't use align-to in the popups (though
we could, for space-only offsets, now that I've read about this spec;
not sure if the change will be worth it, performance or memory-wise).
And as for align-to's used in the buffer text, we probably don't support
them very well, but the proposed change shouldn't make it any worse, I
think.
