Chicken is not shut out.  It just means that WG2-conformant programs
have to use "er-macro-transformer" explicitly.  What happens if you
don't use an explicit transformer is outside the scope of the standard,
so Chicken can treat that as implicit ER and other implementations as
something else.

This is the advantage of standardizing a facade rather than what lies
beneath.
