I'm not exactly sure what that would achieve...but I feel like it would offer more flexibility in this particular scenario!
Not being able to drink from a garden hose would make me feel sad, though.

I think cost would be prohibitive. You add about 40-50% more steel for a given volume to have two pipes instead of one. You’d also have a retrofit problem where existing pipes wouldn’t be twinned. I’d suspect you’d never make up the capital investment.
