I think it would be useful to put "all" the latex commands/references/symbols into a wiki that lets you build ontologies and have metadata. In particular, I think something like Semantic Mediawiki would be useful. Here's why:

* You can create templates and forms to easily add and edit references
* All of the templates and forms will store the data with appropriate metadata.
* You can display the information on the wiki easily using inline queries
* You can then query the wiki using a SPARQL like syntax and get the results back in many different formats (CSV, RDF, JSON, etc).
* You can easily build groups of symbols/functions and extend the data structures at a level in which you don't need to be a programmer and almost anyone can help to maintain it.

I'm in the process of putting together a set of templates, forms, and metadata constructs to organize the comprehensive latex symbol list in this fashion as we are using latex in our FlexBook system at http://flexbooks.ck12.org. As I make progress on this work I'll update this list so that the bullet points can be better understood with a real example to look at.

As far as I could tell, the miwie stuff was basically a docbook
translation of the unofficial latex reference manual in texinfo,
originally written for 2.09 and updated by various people over the
years, most recently me -- http://home.gna.org/latexrefman.

This is the project I had in mind when I asked my question.  I made
quite a few updates to it over the last couple years, so I think it is
"newer" than miwie; I added many 2.09 commands but had no luck finding
any 2e list.  Hence my question.  I did not have any precise
"specification" in mind.

Of course the "latexrefman" is purely unofficial, but of course if the
latex group itself has the wherewithal to maintain something along those
lines, then that would be vastly preferable :).

Thanks to everyone for the info about the command index and all else.
