dev_appserver Python3 Windows support plans?

[Jay Wolberg]

I have a bunch of Python27 App Engine apps that I have been wanting to upgrade to Python3.

But my development environment is on Windows, and dev_appserver is not supported for Python3 even though P27 was sunset years ago. This makes it extremely painful to re-write and test all the necessary modules, datastore, memcache, authentication, etc. 

Is there a planned support for this?

Windows 10

gcloud SDK 394.0.0

app-engine-python 1.9.100
app-engine-python-extras 1.9.96
beta 2022.07.19

core 2022.07.19
gsutil 5.11

GCLOUD COMMAND:

dev_appserver.py --runtime_python_path="python27=C:\Python27\python,python38=C:\Python38\python" C:\Users\*****\workspace\********* --port=8080
