I'm not a big fan of it personally, all titles in English feel like they fundamentally belong in the past. In a time when everyone generally referred to each other by last name and the titles actually conveyed important information about the person you were referring to, namely whether you mean the patriarch of the family Mr. Smith, or his wife Mrs. Smith (who doesn't use her own name in official paperwork at all generally) or his son Mr. Smith Jr, or his daughter Miss Smith, and so on. These days we would just say John and his wife Jane and his son Johnny and his daughter Dorothy, and if we're being formal we'd use first and last name. And yes we'd include the titles but at that point they feel somewhat vestigial.
