Every time I see metrics being dismissed in response to someone pointing out perceived bloat, I'd love to see what _other_ metrics they are using instead.

Bloat != perceived load time.

The only thing I've found these metrics useful for are baselines for regressions over time.

"Perceived load time" is not a panacea, and not a substitute for actual metrics. Do you actually go interview users on what they perceive? If one doesn't, and is instead just looking at the code _they_ wrote and thinking "yeah my code feels fast", that's biased, unscientific, and objectively an inferior quality assessment strategy than just looking at TTFB/TTI/etc and deriving conclusions from those hard numbers.

The only people I see obsess over these metrics have either their ego or pay tied to them.

Yes, regularly, because that's what effective teams do. I also limit bandwidth to 3G and record the sessions so that everyone can share in the learnings, which very rarely circle back to things like TTFB/TTI.
