Anybody proposed an optional parameter for the default value to `#all?` and `#any?` ?

Feature #12110: Create a method to avoid vacuous truth?

----------------------------------------
I often find myself running into unexpected results when using `#all?` for example
```ruby
[].all? { |e| false } # => true
```
Even though it's logically correct could we have a method that express the following?
```ruby
foo.any? && foo.all?(&:bar)
```
