The reason is that since moving to linking libraries rather than
building code we now have the ability to call functions like
parse_events - previously parse_events was stubbed out because there
was no way to build lex/yacc code. Calling parse_events is more
sensible than existing logic that does things like open a legacy
cycles event only on 1 PMU type. That is, the existing code doesn't
support hybrid. Practically there is no way to test python2 support
builds and works without having python2. We shouldn't be in the
business of installing python2 in 2024, my organization has removed
all support for over 3 years.

Thanks,
