Definition of "non-crushable object"

[Big Mo]

Was looking through the rulebook and recalled rule B3.22 about objects ahead of the bulkhead. The rule presumably blankets a lot of objects, but the examples used are all potentially dangerous objects (batteries) or components needed for safety (brake MCs). The three examples all carry fluid of some sort, too. The structural wing mounts being an exception to this rule cloud it further in my opinion.

My question is this: does "non-crushable" refer to a physical property of the component or a safety issue?

Thanks in advance for your input,

If you have something in mind, you should clarify w/ the rules committee..but

I read it almost as both.
Wing mounts are allowed because there is no other way to do it. Almost anything else other than bodywork & the impact attenuator are not.
i.e., don't put your radiator up there..
