Infra: consider using plugin services to encapsulate IDE-specifc implementations.

[pq]

As a point of inspiration, we can look to the Go plugin which uses plugin services to separate "SmallIDE" from "Idea" implementations.

This will come in handy in particular for project and module configurations which differ across IDEs.

FYI @devoncarew --- I think this is a neat (and canonical) way to encapsulate product/IDE-specific implementations.

UPDATE: I did some more poking around and feel even stronger that this is the way to go. I'll have a PR out later today with some bones.

Awesome, thanks for the research!

More background: the plugin compatibility doc enumerates the modules we can use for our optional includes.

I think we have a handle on this. (In any event, we're actively considering! ;))
