It looks like the subject was brought up again with a different approach, but I'm not smart enough to understand how its different or the implication of the 5 commits being merged as of 2 days ago:
As pointed out up-thread: it was closed in favor of an alternative approach that kept the setting but changed the default.
You might have also missed that in the middle the project published a statement clarifying its approach to the default policy behavior for relay:
https://bitcoincore.org/en/2025/06/06/relay-statement/ Nice, at least it shows a little dose of listening to the concerns. I didn't really buy any arguments regarding technical debt for keeping a setting like that, because it is very small that it is practically irrelevant in terms of workload. I don't like that it is marked deprecated already, which is why I assume many people downvoted it in addition to their general concerns on this topic. If it gets removed in the near future, then the listening was sadly just fake posturing.
I do wonder though, if the naysayers end up being mostly right in the future whether this change would be reverted or not. If not, such an outcome would clarify a lot of things. Let's wait and see.
