macOS runners: Are any homebrew packages required for normal operation?

[Lord-Kamina]

I'm using the macOS runner to install all dependencies of my project via homebrew. It's kinda slow, so I was looking into caching the homebrew folders and so far, so good.

Problem is, the images already come with a bunch of packages and thus the cache files are much larger than they really need to be.
In the spirit of optimizing my space consumption, I wanted to uninstall all the packages I don't need, prior to the cache generation.

So the question is, are there any homebrew packages that should not be uninstalled because they are actually needed by the runner itself to complete a run?

well. I'm afraid nobody knows.

however, runners are somewhat "ephemeral". it is no harm to delete something. the next run will start with brand new runner. no worry

I know changes wouldn't persist, but I was still wondering if anything might impact the current run.

Anyway, for reference, here's what I've uninstalled with apparently no ill consecuences, so far:

There are several other that I thought might be uninstallable but turned out to be transitive dependencies of some of my dependencies, so I left them in.
