Possibly I should have used the word redundant, rather than fail safe?
Today it is standard to have an alternate air source (back up regulator, etc) on us, which is no where near as streamlined as our single regulator, no SPG hose or console of the early days of diving, but both are dam-sure-welcome additions, IMO.
Redundancy for additional safety and as streamlined as possible. A balance.
