I'm not sure it's so complex. What's the equivalent code for recognising an URL? Regex are implemented in many languages, so this regex is, in a way, a portable library/function in most programming languages. And since it's shared, it can easily be checked way more than any single library would be.

Portability is an orthogonal concern. I agree with you that it's the reason regexes are the way they are but we could have also had better cross platform APIs.

Regexes are still better than cross platform APIs, they're an abstract concept. Just like you can implement a tree or a graph in any language and transfer your "tree skills" or your "graph skills", you can do so with regexes.
