No, because I think the main purpose of the term ‘polyamory’ is a rebranding exercise to avoid negative associations due to Mormons and other groups, to try to make it sound progressive rather than regressive. The technical difference (strictly referring to marriage vs also including other relationships) is not that important.
Terminology clarification: did you mean to say polyamory and not polygamy in this comment?
