I kind of miss the simplicity of early Python's "batteries included" standard library, offering everything from gzip support to argv parsing… but still, with no easy upgrade path, it couldn't last… interesting to think that Perl's CPAN model (package managers) won the day…
I think there's only only other platform that has a "batteries included" approach to features… and it's the web browser DOM, which has to have basically every non-trivial application feature built in, AND every previous version of that feature, for perpetuity.
