That could be a discussion in and of itself, but a "term of art" has inherent tradeoffs. It's saying there isn't a descriptive word in the popular vernacular, so we have to use a word that is less popular to describe something specific to a single domain that won't have a relevant meaning to laymen.
For people familiar with that domain, it feels natural. To anyone else, it feels foreign. e.g.
Great if you're familiar with those mathematical concepts, useless if you're not.
Given Swift's focus on approachability and education, when terms are synonyms, IMO the choice should lean towards the term with a more general usage.
But this is well into the bike-shedding territory so it's definitely not worth losing sleep over either way
