The version 4 address is now a substantial cost when renting a server. It starts getting billed separately, so you can drop it if you don't need it.

The days of getting a free IPv4 address when you rent a VPS are numbered. AWS is already rolling out a plan to charge by the hours for an IPv4 address and other VPN providers are paying attention.
Running servers at home is a good thing to have, but I doubt that ISP cares much about users running servers at home. Users watch youtube and netflix. That's what they optimize for.
