Me neither.

Introducing new keyword has become a recent thing in Python.

Seems Python has a deep scare since Python2 to Python3 time and is scared to do anything that causes such drama again.

For me, the worst of all is "async". If 2to3 didn't cause much division, the async definitely divided Python libraries in 2. Sync and Async.

Maybe if they want backward compatible solution, this can be done by some compile or runtime flag like they did with free threading no-gil.
