This isn’t really a giant set of naysayers IMHO, but there is enough embedded logic in devices that it doesn’t make that much sense.

Either you can survive with some type of NAT or you can’t.  Many of my devices would not be missing capabilities if I had just IPv6 on them with some gateway to reach the IPv4 internet.  I could likely make a short list of the sites that I really need access to that are IPv4 only.  With Amazon/Walmart day, they would be well suited to have a fast IPv6 site :)

It’s just a few operating systems that need to be changed:

windows
linux
various *bsd flavors
macos

I don’t think it’s impossible, but so many things check for  224 > A > 1 it would be a large bit of work to fix those.  This is excluding the routing equipment.

What i’ve learned is that stuff like the netgear/linksys you have at your house spends around ~6 months in the supply chain before it reaches you.  these all need to be updated as well as the “big iron” stuff like cisco/juniper/arista as well as their embedded OS underneath, so maybe QNX or something else ‘odd’.

That effort would need to have everyone moving in the same direction now which seems unlikely.
