Indeed, this is *always* true.
Here's how Darwin put it:
“Hence, in determining whether a form should be ranked as a species or a
variety, the opinion of naturalists having sound judgment and wide
experience seems the only guide to follow.”
He followed this up with:
“We must, however, in many cases, decide by a majority of naturalists, for
few well-marked and well-known varieties can be named which have not been
ranked as species by at least some competent judges.”
..which translates to:
“A species is what a community of taxonomists says it is.”
