Are there some data available about the actual benefit of this change?
Over the weekend, I have quickly gathered some SPEC CPU benchmarks results comparing the different x86_64 versions:

thanks, very interesting results. I admit this gain is even less than I expected.
Yes, the gain is small, but a few percent gain will result in e.g. HPC users to pick another distribution. But yeah, the gain in these benchmarks is really surprisingly small.
Why not just do the -v3 only on Tumbleweed x86_64 and leave Leap as it is. Those that want speed probably are on Tumbleweed and those on "antique hardware" can still run Leap.
To me that seems like a great compromise.
No, that's not a good idea because Tumbleweed is upstream of Leap due to the Factory first policy. If a package stops working on x86_64 v1, then we would only find out far too late when it gets branched into Leap.
