Term of art doesn't really have a clear meaning in general (native English speaker, and this is the first time I've heard this), and it's unclear/ambiguous as to what it actually indicates.
"Domain-specific" is nonsense gibberish to people outside ~computing, more or less.
"Term of art" only implies that it is the specific phrasing used by practitioners to describe the matter at hand.
Use "term of art" if you'd like. I think "jargon" is a commonplace alternative and I like it.
However, I was already familiar with "start of the art" so it wasn't that great a leap.
