Yes I have, Doug, and I've considered that they're wrong. If you see anything amusing in "significant other" then you need to go and join hands with D****l on the joke thread. "Mrs Steve" may be jocular, but at least it indicates that we are a married couple and there's no hint of inequality, condescension or property-owning there (as in "my wife," etc.). "Significant other" is almost as nonsensical as "albeit," in m'humble. ;-)
