Hello,

the implementation of PEP 667 is a part of Python 3.13.0b1.  
I’ve attempted to rebuild all the Fedora Python packages with the new release and found that some of the projects attempt to copy `f_locals`. This, newly, fails as `'FrameLocalsProxy' object has no attribute 'copy'`.  
Before opening a bug report, I’d like to ask whether this is an expected behavior or a regression. It’s not clear to me from the PEP’s description.

Example bug reports to Fedora packages: [murano](https://bugzilla.redhat.com/show_bug.cgi?id=2279983), [bioframe](https://bugzilla.redhat.com/show_bug.cgi?id=2279982).
