Extra dependencies impose burdens on every *client* of the careless pacakge:
- Everybody has to download and store the pacakge, which wouldn't
be so bad for one-time use, but lots of times "rebuild the world"
(including blowing away caches) can be a useful strategy.
- The cognitive load is non-trivial, even in the mythical universe
where every package has readable and useful documentation: not
needing to consider a package's documentation is better than reading
it, for the case that it is truly unneeded.
- Debugging is tougher, especially in the face of auto-included ZCML.
- Auditing the dependent application is harder when there are not-
really-needed pacakges in the mix.
- Runtime footprint issues (RAM usage, startup time) are also
