Better question: Why isn't the best dragon retex not available anymore?
Answer: Because they banned Frozunswaidon because of silly reasons and dumb Nexus mods.
To answer your question: they are the biggest animals and a lot of work, even in 8192x40966 a lot of parts are very stretched and blurry
While it's true that dragons would benefit from a larger sized texture, most people's games can't really handle it. Sure, you have the few people (like some here) with massive rigs, but the majority of people playing Skyrim have modest setups. 4K is really the max for most people, even for the largest objects.
I wouldn't blame Nexus for that one, it's not like they really had a choice. Selling textures that you did not create is a sure way to get yourself banned.
