The problem there is that we've never figured out how to make it scale. Right now everyone builds everything static or as a container because if you depend on anything upstream it will break and then you will be held responsible for fixing it. Communities don't scale, and the Apple/Google alternative of closed app stores are... closed... and also tend to suck.

Making shared libraries and other upstream dependencies actually scale is an open problem in practical computer science / systems engineering.

The fact that commercial interests often have a vested interest in things sucking is a problem all over the place.
