I can't do crosswords in English, my native language. I definitely can't breeze through classical texts. It's important to be realistic on the other end of the scale too.

Criteria like this are way too demanding, and it's one of the biggest problems in language learning that makes people feel worthless; having elitist standards that you "don't" speak a language unless you speak it like a university professor, regardless of the fact that you may not speak your mother tongue that way.

Well there's different types of crosswords. I guess they mean the ones that focus on the language itself (eg. idiomatic stuff) and not requiring some obscure knowledge
