I'm not sure anyone would be using WSL for a server / backend for anything other than testing / development purposes. This approach doesn't make much sense.
As for the container, the question is, why not? As it stands you can already run Linux containers under windows. A popular use case is AI tools, a lot of which are built around python and target Linux environments and are containerised.
But the question is ... Docker already runs Linux containers on Windows, so why do you need Linux in a container in WSL for this application.
If your corporation mandates the use of Windows, why are you touching Linux? Why not develop for Windows native?
I'm developing for a microcontroller so why I don't I run Visual studio on a microcontroller? Obvious obtuse example aside, cross platform development has been a thing since development has been a thing. Just because you're a Windows shop with Windows computers doesn't mean you are developing Windows only software. There's a use case for containers, just like there was a use case for WSL, or for Virtual machines, or for physical machines. It can serve as a useful development environment.
