I can't see why you think --as-needed is fundamentally wrong or unnecessary.
Check out http://www.gentoo.org/proj/en/qa/asneeded.xml
--as-needed has saved tons of time for upgrades like Cairo in Gentoo,
where Cairo had been linked to glitz which is now useless and gone. So
when people upgraded Cairo, all the software that linked against it
(and also unnecessarily linked against glitz) broke because glitz was
missing. Maybe this isn't important for binary distributions. I don't
I mean, I don't particularly care what Debian does. I just find the
fervor with which you fight against --as-needed strange.
