Ageed. I was a bit surprised per Jason's
https://lore.kernel.org/git/109813056.nniJfEyVGO@jason-desktop-linux/
that the removal wasn't kept.
I.e. he was replying to a question of mine asking whether we didn't need
this data at rest, e.g if you save the page. I didn't notice the "<?xml
version..." we emit, which seems to be enough.
I.e. this seems to have always been redundant going back to c994d620cc8
(v220, 2005-08-07), or rather, the character set part of it.
Maybe I still don't understand this, but the commit message seems to me
be conflating whether we send the *right* http-equiv with whether we
send it at all, i.e. if the problem is that XML documents shouldn't be
text/html isn't this correct?:

Of course we might then *also* decide that <meta http-equiv> in this
case isn't needed at all, but isn't that a seperate change?
And won't conforming browsers treat application/xhtml+xml differently
when the page is saved? A long time ago (Idid some web development)
using it would enable pedantic strictness in browsers, i.e. unclosed
tags etc. would be a hard error, but I can't reproduce that locally in
either Firefox or Chrome now (with just the gitweb output as-is with
that http-equiv tweaked).
So maybe it does nothing, or maybe it's just those browser...
