People have been doing that since roughly 2010, so the failures are important to learn why it’s not a weekend project. Adoption is critical for alternate roots, so the first question has to be how something gets enough users for anyone to feel it’s worth the trouble of using: the failure mode of DNS is that links break, email bounces, and tons of things which do server-side validation reject it, so this really limits usage. The other big problem is abuse. Names are long term investments, so there are the usual blockchain problems of treating security as an afterthought but you also have the problem that third-parties have a valid need to override the blockchain (e.g. someone registers Disney.bit and points it at a porn site or serves malware from GoogleChrome.eth). Solving that means that you’re back to trusting the entity which created the system or maybe a group of operators, so the primary appeal is going to be if you can make it cheaper than owning a traditional domain.
