Yeah, this is most probably true.
Honestly though, I don't even know what most of the generic domains are that were created. It's still deeply ingrained in me that any serious website should be using .com, .net, or .org. But... the amount of domains that were purchased just for the purpose of resale at an astronomical value has made so many of those unreachable.
There are some dot-coms that I have wanted for years which have been sitting stagnantly for more than two decades. I'd love to buy them, but there's no way I'd pay the asking price. At least generic TLDs break that stalemate for a lot of folks.
I was afraid of that. If this is common enough, i think it's something the devs can introduce a feature for which would propagate such a change. Doubt it's high on the totem of things to do, though.
