Much ado about nothing. Either works.

Double triggers aren't infallible either. There's always two sears set and there's no inertia weight to help prevent doubling.

The only system that really needs a rethink is the concept of the barrel selector on the trigger itself like a M-21 or a Merkel, or a SKB. Don't touch the trigger until you're ready to fire, right? Some design genius made it necessity to touch the trigger to make your barrel selection, and the idea actually became popular. Dumb.
