I think it would be great the see the app on microsoft store; it would increase the popularity of the app.
Don't know how difficult it would be, but it would also increase 'deployment' options in corporate settings. For those who do device-management via Intune and have configured app-store policies to allow/disallow certain apps.
If someone is interested in releasing the app on this store (or the Apple App Store) I'm fine with it, but I won't do it myself. I can help by providing any necessary info or keys though.
