If every implementor got to choose what subset of the standard to
implement that all code would have have to written in the implemented
intersection. I think that's a terrible idea.
The Haskell98 standard was set so there would be a baseline that
people could rely on.
When I implemented Haskell (both times) there were odds and ends that
I really hated (some of those feelings have changed), but I did it
anyway.

Hello Jon,

It's not an implementor's place to make such decisions -- they can legitimately say "this feature sucks" and tell the next Haskell committee so. If they care enough about it, they can lobby or get on that next committee, but the arguments for n+k patterns /in Haskell98/ were done long ago.
if you really believe in that you said, you can spend your own time adding its support :) i never seen n+k patterns in real code so i understand developers that don't want to waste time just to compliant standard even if their efforts will be never really used
