Totally agree with everything. Definitely will be hard to get people to switch. Also love the monorepo idea you mentioned. It should totally be possible to keep the benefits of a monorepo without the downsides of git submodules. So you should be able to open-source parts of a repo without open sourcing the whole thing. One of the benefits of building from scratch is that this is pretty straightforward. Also the other ideas you mentioned are really awesome. Thanks!
