You should think of the "standard" libraries as those that come with the 
Haskell Platform, which includes stm.

The packages that come with GHC are now the bare essentials needed to 
bootstrap GHC itself. We haven't changed our position on stm at all: it 
continues to be fully supported, and there are no plans to change that.

Unfortunately the removal of stm from the set of packages that we 
regularly build with GHC means that it isn't getting as much testing as 
before, which is something we should fix.  There are various plans afoot 
to revamp our automatic build & testing infrastructure, and testing 
external libraries should be a part of that.
