Initially destined to be replaced with Paint 3D and shift into to the Microsoft Store; Microsoft will soon make it possible to uninstall Paint from Windows 10.
In the latest Windows Insider Build that was released to Insiders of branch 20H1; users noticed that Paint is no longer a system component, but an optional feature component.
The feature is evidently still in the early stages of development, as uninstalling Paint currently yields no effect in Build 18956.
Other changes to Paint in the Windows 20 May 2019 Update include accessibility improvements, as well as introducing the possibility of using the program with the keyboard.
While we can see the point of Windows Server not needing Paint pre-installed, I suspect very few users will take Microsoft up on their offer of ditching the much-beloved application.
