If it's bundled in the official binary installers, it makes little
sense not to add to the source tree, IMHO. First because most people
get one of the installers rather than the source tree (on
http://www.python.org/webstats/, MSI builds win by ten to one). Second
because the few people who get the source tree are experienced users
who will get bitten less by hypothetical quirks or oddities.
Third because otherwise we're probably making things harder for our
beloved packagers ;-)
