This kind of thing, or guidspace.arpa, is not that different in terms of usability / ugliness from assigning a unique subdomain under a domain that has been registered in the normal way. There's also a privacy leak: if you assign a unique subdomain then when a device roams and leaks queries for the private domain, the device can be tracked and correlated with other devices that use the same private domain. I have a terrible mental conflict trying to weigh this privacy issue against the horrible consequences of encouraging people to squat on unassigned domains and use colliding hostnames. The privacy leak probably needs to be fixed regardless, and if it is fixed then there would be a bit less pressure in favour of unwise squatting.
