It's worth clarifying that all of the changes in my patch produce valid HTML 4:
Using 'id' attributes on arbitrary elements is part of HTML 4, and I believe
it has been supported by all non-toy browsers for 20 years.

So the only reason for not unconditionally changing things according to my patch
is if we are concerned about third-party css stylesheets or JavaScript (such as
texinfo-js) depending on the "old" html output and hence breaking if we make
these changes unconditionally.  I also suggest we should make these changes
at least the default (and possibly unconditionally) in a future texinfo release.

When if comes to texinfo-js, I would prefer to modify it so it works with
(and depends on) the "html5" output - I think that would make the texinfo-js
code simpler and cleaner.

I'll let you judge which is more important: the risk of breaking third-party
css/js vs the extra maintainance and documentation burden of a switch.
