Re: Convert some local addresses?
Could I live without doing that? Sure, but being able to do this is very convenient.
But does that convenience outweigh the possibility that you will have to share your public IP address with 10 other customers of your ISP? Because the other way around the issue of insufficient IP4 addresses would be to have ISP-based NAT routers so public IP addresses can be shared amongst several unrelated people. Which would effectively stop you setting up any sort of public-facing server in your home.
