cabal sdist warns about optimization levels

[guest]

For some reason 'cabal sdist' dislikes fast code so much that it tells me not to use -O2. What does it know about my needs and my project?

See below for an example:

$ cabal sdist
Distribution quality warnings:
'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit
and not just imposing longer compile times on your users.

Is there a way to disable this warning in my .cabal file? If not, can the warning please be removed? It doesn't seems appropriate for sdist to tell me which compiler flags I should use to optimize my code.

I think the warning is adequate.
