Complexity is objective, so a numeric measure isn’t good or bad. It’s the rules upon that number that are subjective.
I am curious about why developers find this frustrating. It is very commonly frustrating. Developers almost always claim to want simplicity until the terms are defined, which makes me wonder what they are actually wanting.
I contest that it is truly objective. Some complexity measures are objective. Most merely appear so.
Consider, who wins a sports game is objective and quite simple to define. It is whoever has the winning score. Now, the facets that go into all of the plays and other aspects of the game? Those leave the realm of simplicity quite quickly.
