I agree to remove the reference set... but .....

I would like to see a bit more discussion of an actual draft change to do
that as I think there were a few features of the design that were driven by
the existence of the reference set.

Specifically, do we still need to copy static entries into the header set?

My understanding of that aspect feature was to control the maximum size of
the reference set for zero state implementations.  Now that there is no
reference set and the header table has it's own explicit size limit, can we
just let static references stay in the static table.

There may be some other changes needed because of this - such as putting
the static indexes below the header table indexes?

Eitherway, can we see a pull request?

cheers
