Some programming languages, such as Go, generate symbol names with "." (e.g. git.example.com.mypackage.ExportedFunction), so allow them so they do not become question marks.

$can be used for shell variable expansion,<and>for shell redirection, and@can be used in Bash arrays. And those are already accepted.(I wasn't sure about

Yeah, fair point. Maybe the main goal here is to prohibit characters outside the ASCII graphic set so nobody's dealing with nul bytes or whitespace or invalid UTF-8. If so, I'm tempted to use
