Lawsuits (and the fear of them). Shipbuilding regulations. What's more of a danger to the bottom line, a few places lost to safety equipment and redundancy, or (for example) being told that vessels of that class cannot operate in a given jurisdiction?
The goal is safety of the passengers and crew-members. The question is how much money/mass/volume should devoted to achieving that goal.
Let's look at a current example in the real world, the automobile.
The speed limit for cars range up to 65 miles per hour on most Interstates in the United States.
Should automakers be required to have safety mechanisms built into cars that would allow the driver and passengers to survive a crash with a stationary object when the car is traveling at 130 mph (a 2x safety factor)?
Do they currently?
Are they required to do so, or face not being allowed to sell the car that can't ensure the safety of the lives of the driver and passengers?
If they don't, are not required to do so, why should they?
What keeps them from doing so, if they don't?
I would say that providing a 2x safety margin is cost prohibitive.
Keep in mind the Honorverse is not the Apollo program, where duplicating systems imposed a relatively smaller cost/mass/volume penalty, and where cost was less of an issue than the safety of the astronauts.
Civilian passenger liners and freighters have to show a profit, or they just won't run (as explained to Admiral Caparelli by Klaus Hauptman earlier in Honor Among Enemies).
Also, consider what a 20% life support safety margin would be for an
Atlas that normally carries 5,000 passengers. It is the amount of life support that 1,000 additional passengers would utilize. Since life support is distributed throughout the ship, if you loose the environmental capability to support 1,000 passengers, I would say you have probably suffered damage to your ship that has effectively destroyed it (remember, the
Atlas is a civilian ship, without the armor coffer-damning scheme of a military vessel).
