I'd say it's okay to have it there. And if you don't, it should be explained somehow, since people will expect it to be there, after all it's configured in options.
Personally I'd set any shortcuts which do not invoke commands which change the gameplay to function (Fn with n=1..12) keys, so it's out of the way and you don't hit it accidentially.
It might be a good idea to change some keyboard shortcut defaults in next version (I may do a seperate feature request on this).
