While such licences are free-ish I don't think they would fall fully within the definition of free content (thouh IANAL). Either way they would not be compatable with the GFDL licence, since it does not put any restrictions on who can use a work or for what purpose, and unless I'm mistaken GFDL compatability is the acid test for wether or not something is allowed on Commons.
Not really, even CC-BY-SA isn't compatible with GFDL.
