Reporting semantic tokens for tokens that are not "truly semantic"

Hi ~ I would like to use the semantic tokens provider to replace *all* of the highlighting in an editor, i.e. I don't want to use any other highlighting providers. Unfortunately, at the moment it seems that the semantic highlighting doesn't know about keywords, string literals, comments etc.

Is there a specific reason why this has been decided against? Is there any significant barrier for adding this onto hls?
