Mod support and the Microsoft Store has been a bit of a controversial topic in the past - specifically one of the bigger complaints about exclusivity to the platform is the lack of modding support due to the walled-off nature of the platform.
It seems that there's hope on the horizon though, as Reddit user Pycorax discovered that the latest Windows update has added a folder to the operating system named "ModdableWindowsApps" - if you have the latest update, you can go see the folder yourself now within the Program Files folder.
The update was then confirmed on the Microsoft Dev Center, with the update notes also detailing that app developers can now target their own custom folders.
It remains to be seen how open these new "Moddable" apps will be compared to the current ones, but by moving the apps themselves into a more accessible area, rather than being buried deep within the OS, is a step in the right direction already.
Microsoft have committed previously to mod support for games on the platform, and that games on the platform will be able to take advantage of modding as long as the developer has given support for it. It seems this is the first step on that road.
