My understanding was that base is large and fairly intricate (contains
use of ExistentialQuantification, RankNTypes, and so forth) whereas
haskell2010 is comparatively simple to implement, so there's more hope
that it could be provided by a non-GHC compiler. In practice I suspect
that it's not often used in this way, but I like the idea.
