There are already different thresholds used at different communities, giving different permissions.

Why? Because the local community discussed - at length - the pros and cons and has reached a decision. It's not based on external metrics, the same way *all other current thresholds* were not based on external metrics (neither local nor global).

@Urbanecm (or anyone else tracking this ticket): Is there any response to the question above? Any reason to not implement the local community's wishes, after a consensus was reached supporting the option presented in this thread?

This will still allow everyone to edit. But will set a different threshold for access to protected pages (which are few anyway and only by necessity).

Of course there are changes which - regardless of community consensus - will not be implemented. I've reviewed the link you've provided and I don't believe this particular request falls within any of the examples given of requests to be denied.

The community decided this without basing this on any metrics.

Indeed, this is the will of the local community.
