They are, because lots of them are known to be broken.

GPT was in fact blacklisted for Thinkpads in F16. We blacklisted it for
F16, disabled the blacklist for a while with F17, but enabled it again
before Beta. If you got a GPT install from F16 you must either have done
your install before we instituted the blacklist, installed with a 2TB+
drive present (in which case the blacklist is overridden), installed
native EFI (ditto), or the 16 blacklist must have somehow not hit your
model while the 17 one does.

I'm not sure, but try 'gpt' maybe? I know 'nogpt' exists but I don't
know if there's a parameter to override the blacklist.
