The way I see it, the more we exercise self-restraint in our suggestions, in response to feedback here in PM, the sooner we'll see a release of Perl 6.
If they don't want new features past a certain date, then set that date, or suggest that it occurs. Last I checked, P6 will be done when it's done.
I could see good coming out of suggesting something being put in place. It can cause a new idea for the architects to think about a happy medium between what the architects want and what he and some people like him expect.
