Adding 16 bits or 32 bits doesn't matter: The networking stack of every device would still need to be updated to understand the new address structure (just like IPv6!) You can't magically fit 48 bits in a 32 bit field.

IPv6 was the correct long term approach. You wouldn't want to pick only 48 bits and have to do this again in 20 years.

Every device has been updated. We are still lagging because nobody wants to use it.

Yes. I'm saying if we had to update every device anyway, we might as well do it right and not some short term solution (48-bit addressing or whatever.)
