CentOS 7 supports several architectures:
- x86-64

- ppc64le
- armhfp
- i386
- ppc64
- power9
Perhaps we should start by looking at that list and deciding which of them will be supported in el8.
Are all of ppc64le/ppc64 and power9 all going to be valid architectures in el8?
Is it now time to retire i386 - 32 bit Intel? The last mainstream Intel processors that were 32 bit only were manufactured in 2005. Yes, there are some outliers like laptop chips and a few ancient atoms that were 32 bit only for a few more years but the majority of 32 bit only processors are now 14 years old and will be 24 by the time CentOS 8 goes EOL. I would suggest that this is put out to grass and left to die. CentOS 7 i386 will be still be around until 2024 when those 32 bit processors will be close to 20 years old.
Yes .. no more i386 as a separate arch.
Power9 is now part of ppc64le proper .. in el7 it required a specail kernel and qemu .. in el8, power8 ppc64le and power9 ppc64le are in the same tree. There is no ppc64
So the arches are x86_64 (with i686 multi library support), ppc64le (for both p8 and p9), aarch64 (all upstream arches as well) .. and armhfp as a secondary / unique arch.
We do not currently have a plan to build s390x .. but I would not rule out the possibility.
All but armhfp is also supported as an arch in RHEL-8.
