Additional context
Maybe I find time to create a PR, but would be interesting whether this was already thought of or why this does not yet exist.

Mainly I'm not familiar with taps outside of using them as a user. I'm not opposed to having a tap but I'm not sure I'd like to maintain it.

Currently releases are fairly trivial with just pushing a tag causes the CI/CD process to create artifacts which you can download with a releases for virtually every architecture/OS you can think of. (https://github.com/esnet/gdg/releases)

My issue with adding brew is that it's a slippery slope to start supporting other packages like (.deb, .rpm, dmg, flakpack etc). I'd much rather not have to manage all these package managers unless there's a strong advantage you can see that isn't solved by simply either running:

go install https://github.com/esnet/gdg@latest or the release pages gives precompiled binaries with sample configs.

My biggest argument against it is more of a maintenance overhead rather than the initial work to figure it out.

I looked into this a bit more, it seems like there is a way of doing this with goreleaser which removes the maintenance aspect. I'll need to spend some time on this but: #89 captures that. If you want to try to play around with goreleaser in a fork, I'll happily create a tap repo

This is now done. Feel free to install using a homebrew tap. Instructions are available here: https://software.es.net/gdg/docs/gdg/installation/#homebrew-installation
