What exactly do you imagine that such "recognition" would entail? Are you expecting the IDE to provide its own package manager, for example?

Generally it means "my inspections and autocomplete works as expected".

[zahlman]

It can't possibly autocomplete or inspect based off code it doesn't actually have.

That’s the point. Many modern IDEs are in fact capable of downloading their own copy off some source and praising it.
