Quite. But we're talking about supposedly well-established and widely
understood technologies here: the cgi module first appeared in 1994
(1995 in the library); that relative newcomer the Cookie module
appeared in 2000; BaseHTTPServer appeared in 1995; asyncore was added
to the library in 1999. And unlike various scientific computing
interest groups, those who use Web technologies are so broadly
dispersed across all kinds of other domains that I doubt that even if
GvR told everyone to take their Web modules elsewhere, there'd be
enough cohesion to have such an umbrella WebPython distribution.

Well, I don't want everyone's modules in the standard library, but I
think it makes sense for people to work on integrating modules into the
library that make it easier for them and others to then focus on other
stuff. What if the cgi, BaseHTTPServer and Cookie modules hadn't been
in the standard library? Whilst some people might regard the resulting
dearth of Web frameworks as a benefit, I think you'd see less activity
in that part of the community as a consequence.

But I don't want GvR to bless a framework. Consider his misunderstood
near-blessing of Django: it's almost nonsensical. Sure, Django
innovates somewhat in terms of describing the URL space, but there are
numerous people who don't like the templating or the ORM, so they
wonder if they just couldn't strip that stuff off and replace it, but
what are you left with? The bare platform, of course, which isn't worth
continually redeveloping for each megaframework, but that's what has
been happening over the last five years.

True, and this is where a lot of the marketing Python discussion missed
the point, dwelling on the corporate acceptability of Python (ie. the
nod from the PHB) and ignoring the peer marketing effect (ie. some
colleague you get along with shows you something with a "cool" label
stuck to it). The Django and TurboGears projects have noticed this
phenomenon, in contrast to that other supposed "winner" of the
frameworks war (Zope), but I await the day when some other loudly
advocated technology emerges to expose Python's library weaknesses and
causes a similar reactive scramble amongst the interested parties of
that particular domain.
