This package has no reverse dependencies, and was last updated in 2020,
does it make sense to keep in testing?  Or even in Debian?

It is affected by the go.mod issue:
https://wiki.debian.org/DebConf/26/Sprints/DebianGoTeam/DevPackages

Opening this to have some discussion, maybe we don't need to QA upload
this package.

# The package also ftbfs so to simplify I'm tagging this one as "ftbfs"
# However, if the package is finally not removed, then this ftbfs issue still remains
