I'd like to be able to respectfully disagree with pre-RFCs in a similar way I can agree with it, if I don't have anything to add to it.
While I don't miss this feature for the user forum, the internals forum with its pre-RFCs is more directed at gathering opinions (RFCs on Github also receive and directly beneath the proposal). I don't like the way I currently have to interact with pre-RFCs, that are technically correct, but just don't appeal to me, that is, I have to comment "I dislike this proposal". If someone asks me for opinion, this is appropriate. However, if I'd write "I like this proposal", that is inapproptiate as outlined in the forum rules, which explicitly say to use , if there is nothing else to add to it.
