A significant number of Haskell libraries, both user-contributed and
compiler-bundled (in the "standard" library hierarchy), are not written in
Haskell98, and rely on a number of (typically well supported) language
extensions like multi-parameter type classes + functional dependencies,
existential types, hierarchical modules, etc. Some libraries target a
specific compiler (often GHC).

It should be clear that standardising the popular extensions would make a
greater number of compiler-bundled and user-contributed libraries standards
compliant, which has the obvious benefit that they can be used with any
standardised compiler/interpreter i.e. they become more portable.
