Is this a really problem? It's vanishingly rare in my experience to here a phone ring these days. Rude people intentionally playing music or other media without headphones is a much larger but still rare phenomenon.
I don't know if its a problem but awareness can't hurt.
Is nobody except your wife reasonable about when to send an async message versus when to call? You found an exceptional wife then, at least among that population
Also, not having (group) message pings is not the same as not having pings for synchronous calls where someone actually requests your immediate attention. I have two colleagues who have notification sounds on their phone turned on for our company group chat. I don't know what the people around them say, but I'm bothered by it already when they're in 30-minute online meeting with me. Is that the type of "not practicing DND" you mean?
In my experience, my wife (like many in our generation) doesn't like talking on the phone so she won't call unless it's something time-sensitive. Meanwhile I've even seen some scammers and robodialers call twice in a row.
That's kind of what I was getting at. Doesn't nearly everyone have the same policy already? This custom-agreement-with-wife is what I would call the default.

Wow, how dare they?! That's illegal! ... More seriously, unless those are in your phone book then that should be easy enough to filter out and shouldn't bar letting your contacts call you when they think it's appropriate.
No it is not for a normal well adjusted person.
