I don't think the go module system is great but I am not sure if any programming gets it right and all suffer from many issues, but go has the go.mod and it is easy to see what dependencies are being used both direct and indirect and the user can filter and look though these packages and pin them until they have eyeballed updates to the git repo. I don't feel the most comfortable with it but the whole `curl | sh` is so terrible, no signing no, way of knowing about the integrity of the installer.

I do not think the program really needs and installer but if one must then why not just have it under source control that way you get the benefits of git handling all the download bits and the install script being completely offline and just using cp or install commands.

you could tell the user to do this with a pithy command like `git --depth=1 clone $GITSITE/$REPO && $REPO/installer.sh && rm -R $REPO`
