C is not a holy cow, is it? It's just a very, very popular language. Error handling is important in programming in general, and having ways to implement it conveniently helps a lot.
Yes, errors are just data. And everything is data, including the code itself, right? It a question of abstractions introduced to the language and the program at question.
errno.h is bad. It's inconvenient, it's global, even if it's a thread-local something, it's cumbersome to use.
AFAIK, there are 2 error-related proposals for inclusion. One is making errors special, the other is a bit more generic. Both would improve on the current situation.
