--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
I don't think it makes sense to keep this bug open.
We don't know if other vendors use the exact same feature bits as Intel and
AMD. So checking the vendor name is safer. If we didn't do that and there's a
CPU out there which reinterprets feature bits, glibc might not work at all.
