Options realistically are:
1) bump the baseline 2) provide a second more optimized port.
3) defer this until better tooling is available to implement (2) Since the RFC is about bumping -march to x86_64-v2, it either gets accepted and my desktop computer can no longer run Arch, or the RFC gets rejected and another approach is proposed in the future. Discussing alternative implementations seems out of scope. For what is worth, you mentioned RHEL 9 adopting x86_64-v2 but I'm not sure it translates well to Arch; companies have shorter replacement timelines for servers and workstations so it makes sense for upcoming RHEL releases to target newer hardware. Furthermore, older machines can stay with RHEL 8 until 2029; Arch doesn't have a fallback like that.
