But yeah, I agree that if would be good to define them. :) I didn't know either. The email threads Adhemerval pointed to were quite useful. That's what I think is one of the benefits of watching this list, you learn a lot about new Linux features (and in my case, features that are new to me). The glibc-hwcaps support seems to be present in my Ubuntu 22.04 install, at least '/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 --help' seems to imply that.
