I agree with other responders and want to add, that huge distro automatically becames hard to upgrade and maintain.
in reply to Perl with Everything
When only a small module changes, its not hard to repackage again, its hard to convince people to upgrade again, only because your new script requires small upgrade of small pure-perl module.
Then again, you'll end up with 200Mb initial distro and a number of small update packages, and finally there will be no gain.
