I do think there's an order of magnitude between the impact between
moving some and moving everything. And that's going to impact
cost/benefit calculations.
Moving e.g. all ephemeral files into a (possibly configurable) directory
is going to hardly impact anyone. Renaming pg_logical into something
different (FWIW, it was originally named differently...) will hopefully
impact nobody, excepting some out of date file exclusion lists possibly.
But moving config files, and even pg_xlog (which we document to be
symlinkable somewhere else) imo is different.
The other thing is that the likelihood of getting anywhere by doing
radical one-off redesigns is approximately 0.
