What about the following?

$ src/rm -r src/. src/rm: refusing to remove '.' or '..' directory: skipping 'src/.'

That helps. But I'm also starting to think we should add a new long option --no-preserve-dot, similar to how --no-preserve-root can be used to work around the restriction. Then people that want to can create an alias or other wrapper around rm to get the non-nanny behavior, while the default behavior still complies with POSIX.
