That’s the main issue I see, they can stop the service at any time and then you’ll have no chance to get the subdomain back. You’re in a much better position with an actual second-level domain, because you can move the domain between service providers and registrars, and depending on locality you may also have actual legal rights to keep owning the domain.
Even for newer second-level domains like .lol and cool-looking ccTLDs like .io, the possibility that the registrar is going to end it, become unstable, or change policy is real. They’re marketing gimmicks.
