Cool! Yeah, it is quite annoying when people use extensions when they
have no reason too, many packages need only depend on haskell98 but for
wanting to use dots in the module names. Unfortunately, there was a
misguided push a bit back to 'de-portablize' much of hackage replacing
haskell98 dependencies with base to work around some dependency issue
hackage or cabal or something was dealing with. Control.Exception is a
common offender.

once I have full haskell 2010 support, I plan on disabling much of the
ghc-base extensions by default, providing them as an independent
ghc-base-compat library that won't be incuded by default. So, people can
still compile their non-portable stuff, they would just have to
be explicit about it. It would also allow me to separate out the stuff I
added because I think it is a good idea and needed for a compiler, and
things I added simply for ghc compatibility.
