Agreed, but macros aren't only about hygiene.

I'm not sure I buy this argument that opacity is primarily an
implementation concern.  How is the non-symbolness of identifiers not
primarily driven by implementation?  I know this is again naive, but
the recent discussions on c.l.s. have shown (again) it's a view some
people would like to hold---they don't understand why they can't just
use symbols.
