Of the 372 direct reverse dependencies of haskell98:

http://bifunctor.homelinux.net/~roel/cgi-bin/hackage-scripts/revdeps/haskell98-1.1.0.1#direct

there are 344 which also depend on base (See http://hpaste.org/47933
for calculating the intersection).

Is it easy to check, out of those 344, how many would build if the dependency on haskell98 were removed?  I suspect it's not needed for the majority of cases.

+1 for Plan A, but interested in mitigating the negative consequences.

(Bas, your link doesn't work for me BTW, can't resolve the IP.  May be my uni's dns cache.)
