Why no 1903/08 style shrouded hammers?

I’m looking around to find some info on this but thought I would also bring it up here. Woundn’t this be better for carry in the snag free area?

I have been carry a 1911 for a long time and have never had issues with the hammer snagging. Most of this carry was done with a rounded “commander” hammer and a beavertail.
