The disappearing spare tire

So I've seen a few posts talking about moving from run flat tires to non-run flats. This is obviously a bigger issue for those with a third row seat and no spare tire. HOWEVER, just wanted to point out, BMW's solution to not having a spare tire was putting on run flat tires. Other manufacturers have also deleted the spare tire and gone different routes to address the lack of a spare including repair/inflation kits. Here's an article talking about the spare tire removal trend:

For any one interested, here's a version of a repair kit like the ones discussed being used by other manufacturers. It might make moving over to non-run flats without a spare, a little less uncomfortable and they claim to be tpms safe:
