These are all just your personal preferences. Just use another language instead which better matches your taste, nobody forces you to use C and there are plenty of more opinionated alternatives.

FWIW, the standard library being stuck in the K&R era is an actual problem since it doesn't make use of more modern language features and some functions are downright footgun magnets, but nobody quite agrees what a modern stdlib should look like, so a stdlib2 probably will never happen.
