I agree with you that it should 💯 be a feed preference. most features in my opinion should be readily available and all use a toggle to include or exclude at the users discretion. 

I think where we fundamentally disagree is that I believe deletion means a specific action of permanent removal; it cannot be retrieved. it is probably just a semantics issue I have, but I feel like more harm could come from people misunderstanding "delete", rather than knowing they cannot. 

I'm not sure how this feature will be reconciled in the future, but these nostr devs continue to improve, and upgrade this experience, so I'm not too concerned.
