I think that's the good idea though, we lack a way to aggregate every information we have on a line of particular code. More comments will be valuable.
Yes, but with some minor differences. In Github you have a very narrow window to comment on a line of code, think in a withstanding pull request, before it gets merged, after that the code is kinda all set. This in my opinion has a lot of potential and I would love to help if there is a way.
