I agree with you.  I think the rationale for the status quo is actually
just historical accident, reflecting that the support for #! ... !# was
initially designed only for the `#! /usr/local/bin/guile' line at the
beginning of a script file.  But it surely much more useful for #! ...
!# comments to work as you suggest, and I can't see any downside from
making them do so.
