It really irks me that the de facto rate limiting headers mix camel case with the more standard dashes, i.e. RateLimit-Remaining instead of Rate-Limit-Remaining.
Http headers are case insensitive by spec (but not always as implemented, yay). I'm a fan of ratelimit as a single word, but then they capsed in the middle to hedge, I guess?
it's all lowercase anyway at parse time.
rate-limit-remaining would be nicer than ratelimit-remaining
