Maybe you're right for the bit where (from what I gather from your
comments) nxml-mode concentrates on the visible part of the buffer. Not
unrelated, that's where nxml-mode and Flymake differ in their
promise. Flymake's is to check the whole buffer, letting you know in the
mode-line how many errors you have, and quickly letting you navigate
between them. I think that, by design, that part could never be "as well
as nxml-mode". On the other hand, perhaps it would be useful to ask
backends to concentrate on this region first, then elsewhere.

OK then. I guess I misunderstand the graveness of a make-obsolete.

Done, and rebuilt a prettier history in the branch

Will still fix some more longstanding bugs and then merge to
emacs-26. Bugs and finishing touches can still be fixed there.
