        This is true, although effects can also be influenced by
government type, other active effects and known technologies, so it's a
little more complicated than that. (The "other active effects" bit is the
most tricky, and one of the improvements - in the default ruleset - which
makes use of this cond_eff field is the "City Walls" improvement, which I
suspect a lot of people actually use quite widely.)

        That depends on what you define your "effect" as being. Effects
defined by buildings.ruleset are not sent from the server to the client at
all, since this can reveal information that the client should not know.

        The number of unhappy citizens (and that kind of thing) is sent
in the city packet in the same way as before, so no updates, on top of
what we already have, are needed.
