If you have multiple overlapping standards, then perhaps it would make
sense to deprecate some of them. But we are in the situation of
having only two current standards ('98 and 2010), and they exactly
agree on the contents of these libraries.
Furthermore, the H'98 standard itself states
It is intended to be a "stable" language in sense the implementors
are committed to supporting Haskell 98 exactly as specified, for
the foreseeable future.
The base library package has no such guarantee - it is not supported
in its entirety by all compilers, and it changes frequently. (As one
data point, base changes frequently enough and severely enough to
break my nightly builds of nhc98 several times a year.) In my view
there is no way that base can be called stable yet.
