I was thinking it would have to be one of the new gTLDs, where 'normal' rules don't seem to apply, but I think .co also asks silly money for any remotely decent name, and that's technically a ccTLD, even though I doubt anyone buys it as such. > gTLD's like .land or .tech seem to set premium prices at the registrar level and apply to renewals. This means if I want apps.wiki, it's going to cost me $3,180/yr every year. AIUI premium domains renew at a relatively normal price, so there may be a rule that states they can't charge premium rates for renewals (and therefore decide later your name is a premium), but in the domain world I wouldn't rule anything out. I wouldn't personally use anything but .com/.net/.org or ccTLD for a serious site anyway.
