Penultimate Amazing
No, I understand the need for a distinction. I don't understand the need to repurpose a word that already has a clear meaning.In a star most other elements are present in such small amounts (relatively) that it makes sense to lump them all in together, particularly because pretty much any main sequence star with (for instance) x amount of titanium will almost always have y amount of calcium, etc.
Metallicity (i.e. the overall amount of other elements) is a good indicator of which population a star belongs to and which stars it might be related to.
"Oh, metal," said the astronomers. "Nobody's using that word, right? We can just make it mean whatever we want, right? And then correct anyone who misunderstands it, like it's their fault."
Boop to that. Find a different term.
