Isn't l2-acquisition essentially the purpose of this site?
Could it not be applied to every question here?

Not the entire site is about second-language acquisition; native language acquisition is also on topic. If fact, we have more questions tagged native-language than questions tagged l2-acquisition.
However, l2-acquisition is a very broad tag. Perhaps we should limit its scope to just the second language, to distinguish it from foreign language learning in general and from third-language acquisition, which is a research topic in its own right.
