It's somehow better to have each package require its own separate
configuration than to use a central package that only takes 2MB? I'm
not saying you can't do it, but:

- every mutt user would have to set up their own muttrc with smtp server information
- every fetchmail user would have to change their invocation
- and so on, for each package as needed

Sure, but then you're still breaking at runtime instead of build/install
time.
