Update Single Quickfix list for showing diagnostics.

Is your feature request related to a problem? Please describe.

Currently the LSC updates the active quickfix list. Say I have a quick fix list populated with grep matches, when LSC kicks in it replaces the grep matches.

Describe the solution you'd like

Update / use a single Quickfix list as opposed to the active one, since multiple apps use the quickfix list.

Additional context

I am learning Rust and would like to implement this feature. Some ideas to start would be appreciated. I see there is no direct way to get the quickfix id (which I guess is used for updating). Is there some other way of implementing this?

I have a basic piece of code with a vim script function that returns the id of quickfix list if the title matches. Have modified the rust code to invoke it. But there are synchronization issues. 'publishdiagnostics' is invoked quickly in succession. I need to atomcially do getting the quick fix list id, adding/ updating it. Any advice would be useful.

This is actually a nice idea and it's an issue with quite a lot of plugins: eventually multiple plugins end up overwriting each others' quickfix list. 👍
