The query is a tracking issue for implementing Python 3.10 language features in MicroPython. The candidate PR adds documentation (a python_310.rst page) tracking implementation status of 3.10 features. Documentation of what is/isn't implemented is directly related to the tracking issue, but adding a status page does not resolve or implement the features being tracked. The issue remains open as work items may still be incomplete.
Suggested action
Leave the tracking issue open. Reference this PR as progress (documentation of 3.10 status), but the issue should only be closed once the relevant Python 3.10 features are actually implemented or explicitly deferred.
