Subject: [ruby-core:110734] [Ruby master Feature#19128] Hash#delete could take a second argument as the default value?

Issue #19128 has been updated by sawa (Tsuyoshi Sawada).
Since you are avoiding doing:
```rb
{}.delete(:a) || []
```
it must be the case that you have a hash in which `nil` can be a meaningful value, and you want to distinguish that from the case where `delete` results in a miss hit. What is the use case for that?

e.g. `{}.delete(:a, [])` would return `[]`
