Surprisingly, the only mention of the cannibalism tag I could find was in reference to the Cannibal Yuyuko pool in forum #69923. It doesn't look like there has ever been any in-depth discussion about what exactly the tag is meant for.
Personally, I'd support broadening the tag to include intelligent beings eating other intelligent beings of different species. A strict reading of the current definition would prevent us from using the tag for, say, a human eating an elf, which strikes me as a bit too restrictive.
Is that really what you want though? Bear in mind that sometimes the same base creature can be intelligent or non-intelligent depending on the series, or even depending on the individual specimen within a given series - this would create the bizarre situation where an intelligent orc (or whatever) eating a human is a cannibal, but an intelligent orc eating a non-intelligent orc is not.
Likewise, cannibalism can exist within non-intelligent species and is still cannibalism regardless. Many spiders will routinely eat other spiders of the same species, for instance.
