I 100℅ agree with this sentiment & position.
It extends not just to new features but also "fixing" existing features. I don't like how BIPs are used to articulate & propose both new features as well as fixes/maintenance.
I'm glad someone is talking about this. In my mind taproot was a lesson in being more careful about what is prioritised & the unintended consequences that any change introduces.
As a Bitcoin user (node runner), the only use case that I think is worth pursuing is onchain privacy.
