The QA community is not a security or an risk assessment team.
We leave that part up to security team which possesses the necessary
skill resource and experience to correctly evaluate and assess any
concern raised related security ( or lack there of ) within the project
thus security related questions are off topic for this list and should
be asked on Fedora's security mailinglist  instead.
More information regarding the Fedora Security team can be found here .
As Adam mentioned this has been discussed both on this mailing list and
in some threads and the devel list for example here  here I recommend
that you go through the mailing list both here and on devel to see the
relevant discussion regarding this matter.
