== Detailed description ==
Currently, the i686 RPM packages are built in such a way that they are
compatible with very old i686 systems, such as the Pentium III.  The
only addition over the i686/Pentium Pro baseline is a requirement to
support long NOPs, for Intel CET.  However, the majority of
installations of i686 packages is for use on x86_64 systems, as
multi-lib RPMs.

Based on what data?

The mirror data I've seen, but it's really outdated at this point.

This proposal suggests to accept this reality and build the i686
packages in such a way that they require the ISA level of (early)
x86-64 CPUs.

On which x86 CPU families will Fedora continue to work?

Based on this proposed change, you will need an x86-64-capable CPU.

Thanks,
Florian
