Hi. Thanks for doing this. I was thinking about it a while ago and had thought of many of the same names for the people best added to the list. Sander is a great choice for SVE/scalable stuff and Amara is obvious the right person for GIsel.

I would say - that the list of people we have for Arm is much the same as the people who maintain AArch64, especially for people like Peter with the ABI and anything that isn't "codegen". Many aspects span across all of the Arm architecture not just one backend or the other.

I think I would recommend combining the two sections, even if the result is a little large. This is a list I came up with, providing @efriedma-quic is happy to be on for at least ARM64EC. (The order is roughly alphabetical barring myself, just to make sure Amara didn't get spammed with a every issue). Keeping Tim in is obviously OK too if he would prefer to be kept in, I was just trying to make sure it didn't get too large. Let me know if you think this is useful.
