That is absolutely NOT what he means about the keys!
“to avoid key sharing”. Every program having its own key. However a coordinated approach that can be used with Microsoft to get your own key. Thus avoiding everyone approaching Microsoft using different channels and different methods with resultant duplication of effort and duplication of research on how to actually get hold of the keys.
Just to point out the obvious: with perhaps the exception of iD / Potlatch likely everybody has a non-enterprise account and associated key.
With other words the clock is ticking and the EWG would already seem to be stretching things for many projects as this change needs to be done and fit in to a release cycle by end of June.
