Walter and I discussed this idea a while ago. It's a good one.
To ease into things eponymous templates should work both ways for a while.

We should define a little protocol for ideas that Walter approves but 
has higher-priority tasks to work on. Like DIPs that he gives the seal 
of approval to, so people know they can work on them.
