Instead of putting the message in the startup, perhaps make use of
the BugReports field in the package DESCRIPTION, and maybe use a GitHub
issues page with a good template ....
This way you avoid annoying your users with startup messages, for something
that should be accessible in the DESCRIPTION itself.
