1.1.1.1 wasn't part of the internet either, and, guess what it does today?...

You seem to be conflating owning a legitimate domain name for the purpose of internal use with making the DNS records from that domain's zone public. One does not imply the other.
Buy the domain, know you will never conflict with something, and you're done (bar renewal!).
It's quite amusing you are promoting the use made up TLD names for internal use but previously you were deriding others for doing the same with 1/8 IP space(pre-2010) for the exact same internal only isolated use case.
I'm trying to picture a co-worker telling the team they went ahead and put all the management interfaces in the .burrito domain in order to save the company $10 in domain registrar fees.
Typically the name would be something relevant to your needs, such as the name of the company, or AS number. I think what you don't get is that the public root name servers do not need to have anything to do with an entirely internal dns infrastructure.
Not suggesting icann is going to crash and burn either, but that "real" TLD relevance to what you do in rfc1918 IP space in a network that is not routed to the internet is minimal at best.
Bet you $5 that Google's actual internal dns for the oob, SNMP management, automated provisioning tools which control those 1e100 hosts is not 1e100, and is not a zonefile you can find cached anywhere public. They built their own internal dns for it. Have seen the same at two large CDNs. Their internal authoritaive DNS servers for their management IP space have no connection whatsoever to the public internet or to the lettered root nameservers.
