I think you're inadvertently mischaracterizing Patrick's comments.
Now, contrast that with parrot...
Parrot's a project several years further along, used in production, with tens of contributors, and a lead designer who prefers to design the skeleton of a system before announcing it and showing off code. Aside from the first three, they're not too different (and the first three are a function of time).
There's really no point in distributing a couple of empty header and source files right now. How do you solicit patches from volunteers if there's nothing to patch? Also, the new lists aren't ready yet, so there's a good reason not to announce things on the wrong list.
That's not to say that there's no discussion; see p6i from just today with comments on regex semantics from Larry, Dan, and Patrick.
