You think there's someone who builds from the source and just trusts what we have put in for the defaults in pg_hba.conf..? I've got a really hard time with that idea... I'm all for making people aware of it, but I don't think it justifies being the top item of the release notes or some such. Frankly, anything that starts with "If you build from source, then..." is already going to be pretty low impact and therefore low on the list of things we need to cover in the release notes, et al.
