I do not see where making the change in the spec is going to reduce
compatibility.
On the contrary I think that if we don't change the spec to say what we meant
we will see more incompatibility.
The whole point of Proposed vs Draft is to catch this type of thing. We don't
have a standard yet. Its an errata on a proposed standard. It happens.
If someone has an implementation that has a problem with this that would be
another issue entirely.
