I want to send an empty JwkSet for whatever reason.

- let empty_set = JwkSet {
-   keys: Vec::default(),
- };
+ let empty_set = JwkSet::default();

@tristan957 , I feel like this change is setting someone for failure down the track.
An empty JwkSet is a source of potential bugs - the compiler will not be able to reason because the struct is there, but the keys are not.

Making this explicit during the construction of the set feels safer to me.

I'm not sure how someone could be set up for failure. I am requesting an empty JwkSet explicitly. What are the potential bugs here? How is this any different than the example I posted 1 comment ago?
