I carry a first aid kit but I don't put it under the parcel shelf. If ever I need it (hopefully never) I don't want to have to spend half an hour removing luggage, carpet, ply cover, etc. to get at it. I'm actually thinking of cutting the carpet in such a way that the cover can be removed with the top part of the carpet still attached to it. The near vertical part behind the seat would remain studded in place.
