I'm not convinced we ever *had* a consensus on this. There were
proposals, but I'm not sure a majority ever bought into any one of 'em.
The whole problem of intermixing manual editing and programmatic editing
is just a big can of worms, and not everybody is prepared to give up the
former to have the latter.
You can, if you are so inclined, implement something functionally
equivalent to Amit's proposal today using contrib/adminpack's
pg_file_write --- okay, it's much less convenient than a built-in
implementation would be, but you can drop some variable assignments into
a file and then put a suitable INCLUDE into the otherwise-static main
config file. The fact that this isn't being done by a large number of
people (is anybody at all actually doing it?) suggests to me that maybe
the demand isn't all that great.
