Based on the story I can only predict that there will be approximately one trouble with domains per year and each fifth trouble will result in domain loss.
The forecast is no one of the current domains (with the exception of .onion ones) will work in the next 20 years timeframe, but there will be other domains.
I see it as an imminent problem and can only accept that.
The domain system is managed by the people with the commercial mindset so they optimize they workflow either for more money or for spending less time for the fixed work. If one of the domains requires them to read many silly emails they are happy to delete the domain. There are many attackers who know and use it, for profit (with a strategy to take control over a deleted domain and sell it later as it happened with archive.ec) or just to deplatform a website which they do not like.
Another problem is the domains are used on state firewalls for geo-blocking, some of the domains are blocked in Russia, some other in Australia, etc, while the website is still accessible using other domains. So to say even the active domains are half-dead already.
Unfortunately, any of these two problems prevent implementing some nice features, such as embed codes.
