Continuing the discussion from [Ability to force subscription to a category](https://meta.discourse.org/t/ability-to-force-subscription-to-a-category/66357):

There is a solution for making all new users watch a category by default (and users can change that as they like).

There is also [a solution](https://meta.discourse.org/t/ability-to-force-subscription-to-a-category/66357) to force users to watch a category based on their group membership (and users are _not_ able to permanently unwatch that category as long as they are a member of the group that triggered the watching).

What I am missing is the ability to make users watch a category based on group membership once (i.e. when they join the group) but not enforce if they choose to untwatch. I suppose this would be a matter of extending this plugin to make sure that every user is forced into watching any particular category only once:

Or is there an easier way?
