The problem with this is that if they support apt, where should it stop ? should they support portage, pacman, homebrew, Nix, Guix, yum, dpkg ?
I don't think it is Microsoft's job to provide packages for every manager. They should make an executable and then anyone who uses a package manager can package the program.
Linux releases should be done source only making it as easy as possible for packagers to compile using libraries present on the system; or using a tool like AppImage and packaging everything yourself.
