Ok, will add it to my TODO :-).

And poor little and totally empty advtrade.c.

Yeah, true. So let's check it against original value from ruleset.

Yes, but they are taken as 'duplicate', de-facto obsoleted, even if you still
can build them. This would make that more universal, and even save few cpu
cycles not vainly trying to sell wonders. We should imho move AI less
default ruleset dependent, and this would help it.

I took City walls as obsoleted by Great wall, ok, they aren't. However they
frequently acts in such a way.

It only works for exploring military units however :|. Also somewhat confusing
for newcomer, one would say ai_manage_explorer() is explorer-specific.
Apologies.
