Simply use the package manager of your texsystem. The main requirement
is that it should be up-to-date so texlive 2019
or a current miktex so that you get updates.

There are examples in the package. Your package manager will put them
in the doc folder. The source of the documentation itself is also an
example.

Yes. Also the latex kernel will need hooks and changes to allow this.
But to be able to make sensible suggestions here, more tests are
needed. That's why we are interested in users trying out things and
reporting back problem, suggestions, feature requests ...

Also things are still bound to change. E.g.
the pdf Association has only just published a practice guide
https://www.pdfa.org/resource/tagged-pdf-best-practice-guide-syntax/
and this means that I will have to change the way I tagged the table
of contents in the documentation ;-(

I doubt it, perhaps some parts can be reused but pdf has really rather
special requirements. Beside this tex4ht is imho quite stable, mature and
powerful.
