pyside2-uic deletes existing output file when source file does not exist

When using pyside2-uic, the output file specified with the -o flag gets deleted if the source file does not exist.
Example:

PS C:\some_path> pyside2-uic .\source_file.ui -o .\output_file.py
Error: File '.\source_file.ui' is not valid

while executing 'c:\venv_path\venv\lib\site-packages\PySide2\uic -g python .\source_file.ui -o .\output_file.py'

Accidents happen. If .\output_file.py has been accidentally set to the application file, said file is lost and one is left to start work back at the previous commit.

Could it not delete the existing output file? Some of us work in encrypted disks and cannot easily recover deleted files :-/ Thanks
