its possible to remove the .exe extension to use binaries in windows git bash by specifying shopt -s completion_strip_exe
but podman is not considering that for the completions.

it registers only podman.exe: complete -o default -F __start_podman.exe podman.exe
it should also inlclude without .exe extension: complete -o default -F __start_podman.exe podman.exe podman.
