Yeah that was left out on purpose, since often times the rarer/less-often used type of item might specify more parts it is incompatible with (but not the other way around), because it's more special. You'll see this with some even more rare things, simply because if everything listed everything else it's incompatible with, the lists can get kinda unnecessarily long-winded since you're not often going to have the other thing anyway (or even know what it is in the first place).
If this one is common enough I guess it could be added in there. In all the many years of having these items it hasn't come up before, but I guess I'll throw that one in...
