Consider `RWBuffer<TemplatedBuffer<int> > r8;`
If we left the old condition as it was, then in evaluating the outer RWBuffer,
we'd need to require that the inner element type `TemplatedBuffer<int>` is a
complete type. It is not yet, however. But we don't need to require that the
element type is complete, because the type trait already rejects incomplete
types.
Requiring that condition caused assertion errors IIRC when recursing into
deeper element types that aren't yet complete. Types would attempt to be
completed earlier than necessary. This is unnecessary since the type trait
itself will return false on incomplete types.
"The only allowed types are builtin types or vectors (which are builtin), any
incomplete type is guaranteed to not conform to the concept."
