I agree with you that one can very often get distraced by single events, however knowing that you are frontend/backend bound isn't all that more helpful either.
For frontend you can guess that PGO, BOLT, huge tables might probably help but it's still a blind guess without knowing what to look at next.
Intel's TMA is the only helpful thing here really. Bit sad that AMD and ARM don't provide a way to calculate something TMA-like themselves.
