    I can't see, why pdftex is in texmf, whereas
        its successor luatex is in texmf-dist?

I won't bore you with the historical circumstances that led to this.
I moved pdftex to texmf-dist.  Thanks.

   english/xetexref: This is unofficial reference documentation for XeTeX

It is an independent documentation-only package, therefore it is
texmf-doc like other such things.  Basically, ctan:info packages end up
in texmf-doc ...

   now the user has to search *all* three texmf trees:

I don't think it's worth investing time in debating which things end up
in which tree.  There is no one right answer.  The only rational way to
find documentation is to search via texdoc/locate/whatever, not browse
to some location and "expect" it to be there.  One person's expectation
is another person's total surprise.

The top-level doc.html file (not updated for 2008 yet) was my attempt to
provide an autogenerated (hence should be accurate/complete) index file
that could be searched.  Not that I've ever gotten a single comment
about it, so I don't think it is used.  I admit I don't use it myself :).
So it goes.

We've talked about various ways of improving texdoc already.  Here's
another one: good full-text search of all files (especially PDF).  Now
there's a project ...

Best,
