Bob,
You have a good point. Personally I don't see the same benefit to Handle Ties in Commercial work and wouldn't recommend that.
It does tick me a little to 'dumb down' things with a 2 pole breaker, but the fact is that many people that do Electrical work in homes are less than qualified to do so, and tie handles or common-trip breakers might help save someone.
I wouldn't oppose a code requirement for tie handles on multi-wire circuits in Residential occupancies.
JMO,
Bill
