        I haven't run any speed tests, so couldn't say. However, the
current implementation only allows units to have effects that affect just
them (i.e. they have Unit-range). Effect interdependencies are also
prohibited, so they are not included in the update_all_effects loop. The
only performance hit is having to do an effect iteration during combat
to get attack/defence modifiers (i.e. impr-gen unit effects generalise
all that AEGIS/Horse/Pikemen nonsense, and allow for
shipbuster/torpedo/whatever effects to your heart's content) but
impr-gen does that already anyway.

Probably easier than teaching it to use impr-gen for buildings though,
at least with the current code.
