Interesting.  I would have expected that the likes of me are few and
far between, and easy to ignore for a big company like ARM, Intel
or AMD.

The question is if "users" to ARM Holdings are actual end-users, or the
SoC manufacturers who build chips incorporating Aarch64 cores. I'd expect
most of the latter to want those features so that they can understand the
performance of their silicon better.
