Thanks for your comment on this, Jenda. It does look like a serious obstacle.

However, as with other things, I'd prefer to see it as a challenge to be overcome, rather than assuming from the outset that it is a deal-breaker. I can envision at least two ways in which this problem could be mitigated, and I'm sure there are brighter folks out there who can come up with more/better ways.

I think I hear you saying that we should avoid repeating the mistake PerlMonks made in being based on Everything. Certainly it is the source of a lot of our pain. Nonetheless, I think it could be argued that it is also largely responsible for much of the success of PerlMonks. If "PerlMonks 6" ends up being built on "Everything 6" (so to speak), I don't think that's necessarily an outcome to be avoided. Probably anything we could choose to do in the next few years will look bad in 15 years. I don't think that should stop us from taking action now.
