There seems to be some question about who should drive this debate. But
there is something we all seem to agree on: it is our role, as the steering
committee, to announce the criteria by which we intend to judge the
reasonableness of each potential candidate extension.
So, let me suggest that we start discussing that, and move back to how this
discussion ought to be driven when we are a bit clearer on the criteria.
Richard wrote a bunch of criteria in the wiki page upthread [1]. I think
that they are worthy of discussion. So let me ask the question: do we agree
with all these criteria? do we want to add more?
