I believe each RIR has a separate process for the return of unused space.
https://www.apnic.net/manage-ip/manage-historical-resources/returned-ipv4-address-space/
https://www.arin.net/resources/return_revoke.html
etc.

It's used rarely, but somewhat; when an organization stops paying their 
bill, the RIR might reclaim the addresses.
Most organizations in most regions would rather sell their unneeded IPv4 
addresses, since prices are rapidly approaching US$20 per address.

1. Shortsightedness
2. Developers hacking together what they barely know
3. Using an OS designed for embedded systems that's based on a very old 
Linux without IPv6 support.

5G is still in development, but I really don't know.

Because as an open body, IETF content must be available to everyone, and 
not everyone has IPv6.

Any general content will need to be available over IPv4 until at least 
2024, when 90% or more of the world is IPv6-capable. Within the next 
couple of years I can imagine a phone app designed exclusively for users 
in the US that was only IPv6-capable, since US mobile is nearly all 
IPv6. Same for India, maybe, and a few other countries.

No: examples include Facebook and LinkedIn, which have very functional 
edge translation from IPv4.

Well, there was a marvelous presentation by Mythic Beasts at v6ops at 
IETF101-London.
https://datatracker.ietf.org/meeting/101/materials/slides-101-v6ops-ipv6-only-hosting-00

But if what you want is for someone to sacrifice their revenue or 
increase their costs For The Good of IPv6, I would not expect that to 
happen.

I have some for Montreal, even though I won't be there. :-)
