Unconditionnal recursion not reported when using derive macros

Code

#[derive(Default)]
struct Thing(Box<Thing>);

Thing::default() // unconditional recursion leading to a stack overflow

Current output

N/A

Desired output

Rustc should print the unconditional recursion lint and maybe recommend a rewrite in some way?

Rationale and extra context

In this case I meant to write Option<Box<...>>

Anything else?

playground

Start by reproducing the Thing::default() example with the linked Rust Playground and the reported rustc nightly version. Trace how the Default derive macro-generated implementation is handled by the unconditional-recursion lint; done means the compiler reports the recursion for this case, with any rewrite recommendation matching the issue's agreed scope.
