Yes, in general sharing more code between those modes would be great.
nXML's indentation algorithm is indeed one of its main weaknesses in
my experience.

Yes, please!

Not sure what this would do which the default fill-region wouldn't do
(once the indentation is improved)?

If I may add a personal wish: make it a bit more permissive with respect
to details of the header (or better help the user fix those headers) so
it's easier to use it for HTML5.
