This is an interesting point. We have to assume that the majority of proposals are not going to be adopted. Will enough be adopted that people will get the morale boost from knowing that the community at large was listened to and gets a say?
Regarding collecting the ideas, I believe you’re saying not to solicit more ideas, but to approach people who have already made suggestions and invite them to participate in the trial. That way we can compare if they felt more satisfied with the proposal process or if they feel like it ends up being more hoops to jump through to still get turned down.
On the product team side, I’m curious what the current process is for deciding what to work on. Is the current process very similar to the proposal, but is mostly done internally? Or is it done in a totally different way? It could be that for the teams this would also be an experiment in using proposals at all.
