[tex-live] what's about biblatex

[Karl Berry]

    But I had the impression (see siunitx or I don't which one of SI* it was) 

BTW, siunitx is now in TL, per the author (the prolific Joseph Wright)'s
wishes.  And it's not in exptl any more, either.  Two non-coincidental
things ...

    for stuff in ctan/experimental we usually ask the author what he thinks.

And by default we leave it out.

And further BTW, the LaTeX 3 packages are not in exptl (any more),
though granted they are experimental in nature.

    biblatex

Right, if the author explictly does not want us to distribute it, we don't.
