I assumed (as perhaps Dirk did) that you meant that it should not depend on
GLSL ES drivers. The only other way I can interpret your argument is that
you don't want it to depend on the language at all. Isn't that a circular
argument? I.e. you don't want the spec to depend on GLSL because you don't
want the spec to depend on GLSL. Could you please clarify this argument?
Perhaps I misunderstood.

See point 1. If the first argument is circular (i.e. not an argument), then
this doesn't follow.
