Unintentional, but I'm not sure it needs to be fixed.  As Xidorn says,
the presense of 'symbols' or 'additive-symbols' is actively
*confusing* for the override system, so requiring them not to be
specified seems fine.  It seems acceptable to allow a useless property
for the other systems, though.

That said, I'm not opposed to making the rule invalid in those other
cases as well.
