Any interest in a Docker build container. For CI or single dev builds.

Is there any interest in a dockerized build? I'm playing with the source and using a docker container to do my builds because I'm on an M1 mac and the toolchain sucks for it. So, I'm building in a linux (arm64) container. I could clean this up and make a PR. I just don't want to waste the time if the project isn't interested. I'm working my way through the other GBA repos too and probably the GB/GBC ones later. NDS and up probably won't happen while that build needs to run on windows with the official SDK since I can't put that in a public docker container.
