Apple sure has some balls axing 32 bit support while still promoting those games/apps on the front page of the App Store. This makes me pretty mad that people not in the know are going to get ripped off on buying apps that won't be supported in a few months.
I thought that too. I've actually decided to keep my iPad Air 2 at iOS 10 as I've spent the last week or 2 going over my 'back catalogue' & discovered literally hundreds of apps that'll die with iOS 11. As you mention, not everyone will find that out until it's too late.
