Yeah, it implies that lifesupport isn't the same as your remlok (the visor thingy), which it should be as that's what gets extended when you upgrade lifesupport. It's possible that lifesupport covers both internal cockpit lifesupport as standard and also the remlok by extension, but that should mean that when it fails/is destroyed - you're dead.
I'd bug report it and let FD make a judgement call, never had an NPC take mine out (they always go for thrusters (grumble

)) so kudos for a unique/rare modular incident
I believe it's a miss-interpretation of 2 things.
You have 2 life-supports on your ship, the main one that recycles the air inside your ship, and the emergency air-tanks when there's a breach in the ship.
When you upgrade your life-support, you're pretty much extending the size of the air-tanks (supposedly near your chair), this one is limited to some min. depending on which upgrade you have.
Then you have the normal life support (which you can target) which is pretty much the canopy, that once you blow it, you destroy the canopy and therefor activate the emergency life-support.
I can be wrong, since i never tried targeting life-support, but i did get my canopy blown up 3 times so far, 2 on beta 1 on gamma, and i believe i saw my life-support system destroyed when i went to repair, i could have imagined tough.
Might grab a sidewindy and go test it tomorrow
