While I am all for flipping these options on, GCC_PLUG_IN options are
hugely problematic in practice right now, to the point that I am going
to have to disable the previous batch before I rebase stable Fedora
releases. Until upstream is willing to accept a patch to ease that
pain, I would rather not add to it.
