[Taxacom] Animalia or Metazoa?

Jim: that's a very general comment, but specifically:
do we really need a "good name" for the diphyletic grouping of
Metazoans and animal-like protists?
Two reasons why we might do:
(1) both come under the Zoological Code of Nomenclature, and
(2) at least the journal Zootaxa also publishes on what it still calls
"Protozoa" (but then, also still uses "Pisces"!)
At any rate, even if we do need such a name, does it have to be
"Animalia"? I am not denying some pragmatic utility to having a name
for the above diphyletic clade, and indeed I would suggest calling
them "animaloids", or something! I just think that there has been some
"slight of hand" in the big Hennigian reshuffle, whereby what was
subkingdoms Metazoa + Parazoa, suddenly became "kingdom Metazoa"
(yuck!), and the old subkingdom Metazoa now seems to be called
Eumetazoa, leaving the poor animals out in the (Hennigian) cold!!!
Animals are such a central concept in everyday life, that surely we
can save their status as a scientific concept (i.e., monophyly) from a
merely semantic assassination???!!!
There are similar issues with the names Insecta and Hexapoda...
