I'm not buying into any of your arguments here, and have something to
add to that part:

Given a conf.d option in /etc it's then quite easy to add per-extension
configuration files in the packaging system, so that users don't have to
edit postgresql.conf for default values.

We still need some kind of repeatable settings that we don't have yet
for that to happen: cumulative setting of a "list" GUC such as
local_preload_libraries and suchlike.
