My entire involvement around Fedora is based on the fact that I was able
to use machines that had been thrown away because they were deemed
‘too old’. I have several servers and multiple laptops that run
Fedora perfectly and none of them would meet this requirement,
effectively ending any chance of using Fedora going forward.
Perhaps as a compromise there could be a ‘regular’ 64-bit and a
64-bit-optimized-for-machines-made-after-2013 version?
