.ro (Romania) changed their policy in 2018 I think. Not that popular, unless your niche. You'll also find grandfathered .ws domains with like, an expiration date 100 years from now.
Sole reason for reviewing their policy and change of RA, the renewal money making machine + aftermarket when the tlds matured. Not sure if
@jmcc is active here but he could shed some more light on this I'd reckon ( go buy his book I might add).
And yes. Haven't noticed any issues. Existing regs grandfathered. But you never now. lifetime + unlimited simply doesn't exist.
There's a whole world beyond GTLDs and newTLDs. ccTlds are interesting and some registries are lightyears ahead of the likes of verisign.
