Confidential merge requests

Problem to solve

People need to propose and discuss changes, without the changes being public. We support confidential issues for discussion in the abstract, but sometimes it's more effective to discuss actual proposed changes.

Further details

I have no idea how this would work, but it would be a great problem to solve.

Proposal

What does success look like, and how can we measure that?

(If no way to measure success, link to an issue that will implement a way to measure this)
