Surely in the event of an emergency requiring the whole nine yards, slides 'n' all, there would be more than enough medical personnel available on the ground to triage those in need to medical assistance from those who don't.
So your "interesting point" is somewhat moot I would suggest.
With respect, that may well depend where said emergency takes place. There are some countries where I'm quite confident I could get prompt access to the meds I need and there are many countries where I would have serious doubts that this would be the case. Luckily for me I don't need to take my bag but can quickly extract my meds from it.
