If your application can't be installed through a package manager, a lot
of end users and every system administrator are going to pretend it
doesn't exist. Using stack/sandboxes hides the fact that the ecosystem
is broken from the developer, but it cannot be hidden from the end user.
Please make sure any such breakage is not your fault =)
