<index> may be appropriate for variable subscripts, but
I don't think it makes much sense for chemical formulae.
I've never heard of the subscript being referred to as
an "index", but I have heard variable indices being
referred to as "subscripts".

Depends on how it's implemented. If the definition is changed to
allow
   l {display: block}
as the default, then no, it would not have the same effect as <br/>
because multiple <br/>s will create empty line whereas multiple
unstyled empty blocks will only create one line break. (An empty
block with no padding, border, or margins has no height.)

If I want to link to _python.org_ in the middle of a sentence,
what element would I use? (It's a reference, not a variable or
an emphasized word.)

I don't see a strong reason to take <h1-6> out, and so IMO
it should be preserved for backwards-compatability. It may
also be useful for unstructured texts that have headings
but no definite sections.

I'd like to note that the latest version of DocBook has
numbered sections in addition to a <section> element. However,
the Simplified version (afaict) does not. The WG might want to
ask the DocBook Technical Committee about their reasons for
keeping/dropping <bridgehead> and <sect1> et al.

I believe that comment refers to the practice of duplicating
the title's contents in an <h1> header.

I suggest
   section { margin-left: 2em; }
for UA's default rendering.
(Of course, language direction would need to be taken into account.)
