People are smart enough to install the software and the plugins they need. If only .1% of the users use a feature, it doesn't have to be maintained by the core contributors (and slow down the other 99.9% users from getting important features and bugfixes). It's a tradeoff and FWIW, while I think postgres is great, I also reckon the tradeoff could be improved.
