Subject: [ruby-core:97530] [Ruby master Feature#16175] Object#clone(freeze: true) is inconsistent with Object#clone(freeze: false)

Issue #16175 has been updated by jeremyevans0 (Jeremy Evans).


I'll work on implementing this after https://github.com/ruby/ruby/pull/2954 is merged or closed, as I don't want to cause conflicts for that pull request.

----------------------------------------
Feature #16175: Object#clone(freeze: true) is inconsistent with Object#clone(freeze: false)
https://bugs.ruby-lang.org/issues/16175#change-84691

* Author: zverok (Victor Shepelev)
* Status: Open
* Priority: Normal
----------------------------------------
In #12300, the new keyword `freeze:` was introduced, allowing this:

```ruby
h = {}.freeze
h.clone.frozen?
# => true
h.clone(freeze: false).frozen?
# => false
```
Though, it turns to me that behavior is not symmetric:
```ruby
h = {}
h.frozen?
# => false
h.clone.frozen?
# => false
h.clone(freeze: true).frozen?
# => false -- I expected true here!
```
I wonder, if it is "by design" and should be addressed in docs, or just an implementation inconsistency that can be fixed?
