> Posix shell-compatible scripts will also likely work on all platforms where you go program would've been run.
While I see your point, writing a Posix compatible shell script is not trivial. Little errors creep in that "work on my machine" because /bin/sh is a symlink to /bin/bash, but break the script when someone runs it on macOS.
In my experience, you get a lot of cross-platform compatibility when writing Go for zero effort.
If a static binary's --help doesn't tell me where the repository lives then I hope the author steps on a lego.
This is a good idea, will add this to my cli tool :)
It is no help to you or your team if they step on the Lego, though.
I mean this entirely depends on how things are done where you work. I wouldn't think the back-reference is necessary if all projects have their own repo in some central location (and it's trivial to match the binary's name to a repo).
Or just make sure the source is available.
