I see two possible reasons for having it (along with other boot libraries) still on Hackage:
1) An archive of previous versions
Archiving the packages is good, and especially making to documentation available for other packages to link into. It seems this would still be covered if everything else was left how it is, but the .cabal file for the packages were removed from the package index in 00-index.tgz. Having found http://hackage.haskell.org/trac/hackage/wiki/HackageDB I'll see whether that's as easily done as said.
2) In case some other compiler one day supports TH.
I don't know of any concrete projects along those lines, so this doesn't seem to argue for anything beyond point 1). I suppose another project probably would want to share the template haskell source, but I expect it would end up being part of their equivalent of boot libraries. Brandon
