In certain places we were bailing out for types without type arguments, but those bailouts are wrong now that we check array subtyping. Also, for identifiers, we now get the type from the Symbol which is more reliable.

A couple test case suggestions, but overall LGTM

To be clear, the type of foos here ends up being Foo<T>[][] right? With a single element array passed in 311 that gets converted to the type @Nullable Foo<T>[][] (meaning a two dimensional array of nullable Foos), correct?

Yes, that's right; added a comment in 4aa9da7. Note that we don't have support for multidim arrays yet in JSpecify mode, so we can't yet test passing in a @Nullable Foo<T>[][] array directly.

What about: takeNullableFoosVarargs(p1, p2)? (also worth having the case for takeFoosVarargs(p2, p1), I guess)
