Should we have a tag for ideas about safety improvements?

Question

There are quite a lot of questions that bring up an idea for improving the safety of commercial aviation, and ask why the idea is not implemented.

These questions tend to have similar answers: namely, that commercial aviation is already safe enough, and implementing the idea would provide a minuscule safety benefit (or would even make things worse) at significant expense.

Should we have a tag for all of these questions? Perhaps we could use safety-idea.

These questions include:

• Why are commercial flights not equipped with parachutes for the passengers?
• Why don't commercial jet aircraft have a break-apart, parachute escape system?
• Why not just drop an engine on fire?
• Why not increase the number of Flight Data Recorders and add jettisoning capability?
• Why don't airliners carry radar jamming technology or missile counter measures?
• What reasons exist for not designing airplanes with breakaway wings for crash safety?
• Why don't big commercial planes have full aircraft parachutes?
• Why don't commercial aircraft adopt a slightly more seaplane-like design to allow safer ditching in case of emergency?
• Why are movable rocket thrusters not used in airplanes?
• Could ejector seats save lives in commercial aircraft?

Answer 1

I fail to see the benefit.

Either these questions are, as you stated, basically answerable with opinion - "Unlikely to be worth the weight gain" - which makes them bad questions.

Or, they are "I've had this great idea - do you agree its a great idea?" which are also bad questions in my humble opinion.

safety-idea (or something similar) has a whiff of meta-tag too. Does it stand on it's own? I do not think so. Is it a GA safety idea, or a commercial safety idea? Does it refer to helicopter operations or fixed wing? Some other tag would need to accompany it to make it a well-tagged question.
