I am cli/vim guy - that’s my daily tools. Starship is very stable and it is useful for me. The only problem I have experienced is with custom extension I wrote myself (problem was slowness not stability).
If you need to invoke a program for every prompt, when the alternative is to just let the shell do it's thing, it's no longer "minimal", period.
No, we are not. "minimal" has a defined meaning, and "minimal" and "minimalism" as a design philosophy are not the same.

I see one dictionary definition is "the least possible". Seems like the least possible prompt is no prompt at all, but it's really just a matter of opinion ;)
