Unchanged.

The original point, I believe, was to achieve 100% savegame compatibility
with savegames older than 1.9.0. Notice that data/classic/ only contains
terrain.ruleset, it has nothing to do with civ1, AFAIK.

It was in 1.9.0 that terrain.ruleset was introduced, and the
data/classic/terrain.ruleset preserves the pre-1.9.0 terrain for pre-1.9.0
savegames. This is what NEWS says about it:

 - New ruleset support for TERRAIN, and changes to allow Civ2 style
   terrain with more specials, multi-terrain rivers, and new farmland
   infrastructure.  Moved some server options into terrain ruleset,
   and added new rule option regarding movement along rivers.

It is redundant because pre-1.9.0 savegames are now so rare (if at all in
existence, let alone use), that we can afford not to support them 100%.

I simply do not know what happens if you load a pre-1.9.0 savegame. I
don't have one, so I can't test. I do not believe it would crash or
otherwise become unplayable, but that's mostly intuition.

No. You just drop the file you want to change into a new directory, then
tell civserver "--config mynewdir". All the ruleset files it doesn't find
in your new directory, it loads it from default/ instead.
