But on windows with the python.org installer, the behavior is same for both both a2 and a3.

# With a3 installed

> py -m venv venv_a3
> venv_a3/Scripts/python -c "import sys,os.path; print(e := sys._base_executable); print(os.path.exists(e))"
C:\Users\ss\AppData\Local\Programs\Python\Python311\python.exe
True
> cat venv_a3/pyvenv.cfg
home = C:\Users\ss\AppData\Local\Programs\Python\Python311
include-system-site-packages = false
version = 3.11.0

# With a2 installed

> py -m venv venv_a2
> venv_a2/Scripts/python -c "import sys,os.path; print(e := sys._base_executable); print(os.path.exists(e))"
C:\Users\ss\AppData\Local\Programs\Python\Python311\python.exe
True
> cat venv_a2/pyvenv.cfg
home = C:\Users\ss\AppData\Local\Programs\Python\Python311
include-system-site-packages = false
version = 3.11.0
