@MarkCarver the only thing I would change is we will have other linting rules. So maybe instead of specifying one layout problem we like 4 spaces we say all editorconfig and linting rules. I think we should require an editor that uses editorconfig whether builtin or through a plugin, and then once we add linting we specify that needs to pass too.

[markhalliwell]

Sure.

While specifying to this level of detail is not inaccurate, I don't see this as a blocker for this PR.

I'm less worried about the documentation aspects as these will, undoubtedly, evolve quite a bit over time.

This at least gets this going.

Yeah agreed don't think any of what I said should be a blocker. Its infinitely better than what we have now that's for sure.
