go get: installing executables with 'go get' in module mode is deprecated.
	To adjust and download dependencies of the current module, use 'go get -d'.
	To install using requirements of the current module, use 'go install'.
	To install ignoring the current module, use 'go install' with a version,
	like 'go install example.com/cmd@latest'.

As modules user this is highly confusing for me as I did not intent to install executables, much less as part of a dependency.
As module author I would wonder what to do to make my consumers not subject to this hint?

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

For questions please refer to https://github.com/golang/go/wiki/Questions

@seankhliao I feel this is the right place. The issue here is that updating a module for go.mod triggers an (invalid) install warning. This happens for modules that provide both packages and binaries apparently.

The fact that it is confusing is why there's a deprecation warning. It also mentions the other commands users should (have) used. See also #43684
