My problem is that it uses a letter as a modifier, while all other
letters are object specifications. '+' is a modifier. We need another
modifier that isn't a letter. No one knew \dtS worked because 'S'
doesn't look like a modifier.

I am also happy with the existing behavior. Another idea is to add a
modifier that supresses system functions, etc.

I think adding 'S' to \df confuses more than it helps.
