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.
