Typically we have a remove action that removes a subset, with a payload that looks like this: +payload: { +ids: $ReadOnlyArray<string> },. Can we do the same here?
This will be useful for example for delete account action, that returns an array of keyserver ids to be removed.

Can we take the whole store here? It seems odd that we call this "process store operations", but only process a part of the store.

This payload and the next are not read-only

This input obj should be read-only

I was introducing +payload: { +ids: $ReadOnlyArray<string> }, in other stores because it was a use case for this. In this reducer, we will either remove only one keyserver or remove all (we have a separate operation for it).

But since it was also requested by @marcin in D10775 I can refactor this.

We are doing the same for ReportStore and UserStore, so I think it's fine. If you insist I can update this but I would prefer to do it in a separate diff or D10773 (I know it's a bad convention but if I change this here I will have to update all diffs in the stack, so making this change in the separate diff or the end of the stack will save lot of my time)
