I don't understand normal peoples obsession with keeping their old SMS messages. I get that there are some cherished memories from loved ones living or passed, but, take a screenshot to be saved to the 'cloud'. And I'm even text-heavy when it comes to communication, but there are no conversations I have over SMS that are worth "re-living the moment" (in my experience). I've got Signal configured to delete any messages older than 3 months. Long-term important information isn't for SMS. I asked my son's friends if they had each other's phone numbers in case the 'party' got split up and needed to arrange to meet at a time/landmark. They pretty much all said "we've got each others insta". Today's yoof don't SMS, so SMS integration has a decreasing lifespan. People's lives are so busy (I know this because that's what everyone says), who's scrolling back through their SMS conversations, and why?
