Those restrictions would be, in my opinion, a good idea. Rejecting
say CC-SA (CC0 is FSF approved), etc. code means rejecting licences
with clear and documented problems in them, problems which would
cause quite a lot of headaches down the road.

Having to pick a licence from the bazillion ones [1] approved by the
FSF or the OSI streamlines the choice and avoids licence creep with a
minimal risk of scaring the uploader away.

I must admit, as fr33domlover notes, that this problem isn't present
in hackage as now (I yet have to meet a library not licenced as GPL/
MIT/BSD3), but after finding this gem on github

    <Software> may be used in commercial projects and applications
    with the one-time purchase of a commercial license.

    For non-commercial, personal, or open source projects and
    applications, you may use <Software> under the terms of the
    GPL v3 License. You may use <Software> for free.

I say: "Better safe than sorry" ;)
