It'd be useful to have a way to tell visitors this project still works without having to push commits to refresh the last updates timestamp.
Seeing no updates in 3 months is one thing. Seeing no updates on a project that describes itself as a work in progress is another thing.

I mean, kind-of. One of the problems with CI/CD though is that they're poorly designed for the job they do; see this: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.26....
The TL;DR here is that by structuring your code and storing it in a database structured hierarchically you can solve CI/CD in a MUCH nicer manner: your root node's history becoming a history of the project in a compilable state.
