I am aware of this: https://confluence.atlassian.com/bitbucketserverkb/4-levels-of-bitbucket-server-permissions-779171636.html however I am wondering if there is a way to provide more granular permissions or there is a plan to implement such a thing?

Especially in a corporate environment, when you have certain policies to be followed you would like to avoid that anybody messes with security relevant settings like "Merge checks", "project Permissions" and "Branch Permissions", "Branching Model" or even "Branching Strategies"

I would like to have project admins who could create repos by their own and also manage the reviewers list without being able to touch security relevant settings, which could be only managed by "Admins".
