Nobody should have to "hope" that an article is about something, after reading a referring post's title.
Start flagging this, ingrates.
It sounds a little odd at first, but besides being the simplest to implement in Go, this also solves a problem for which Python needs tools like venv, pyvenv, virtualenv, ... that also this blog post mentions. The sheer number of these tools shows that this is a problem and that maybe that the solutions aren't optimal.
It also offloads most of package management (ie. pip like stuff) to just "go mod".
A specific binary per project also has other benefits in terms of securing the running environment, I think ... I'm still exploring this.
This is not yet in focus, but maybe starting from a totally different position will make some interesting or simpler tooling possible.
