There’s already some precedent for proposals to exist as a forum post for a minimum of 1 week before being submitted.
Perhaps there’s an issue with that not being socialized very much. I think some UI changes in the NNS or other tools could help.
A counter argument is that someone unfamiliar with the 1 week deliberation period hasn’t been involved in many previous discussions, which could be an indicator of a number of things.
For example, someone recently submitted a proposal to register a named neuron and they turned out to be an imposter.
I think more time to get to know people and ask questions about proposals is a good thing.
