Should Collection::get with a default value return that default value if the key exists but is empty?

[digitaltoad]

I would have expected to receive the given default value even if the key exists but is null. Instead when the key exists but the value is null, null is returned ignoring the default value.

ive seen people argue this both ways tbh, a simple solution to force it is to do $collection->get($key) ?? $default
