I should mention that this is just a way to simplify how you contribute to GNOME apps (and libraries/services for the adventurous). We are using technologies that were incubated in GNOME to simplify contributing to GNOME. This includes OSTree, Flatpak, and Builder currently. It's unlikely that jhbuild will disappear for things that require an entire session (shell, mutter, dbus, etc), at least in the short term.
This in no way affects users, or distributions that choose to use something other than Flatpak to ship applications. It's simply a shortcut for contributors to get started without building the dependency tree. No more build breakages in the dependency graph. No more compiling WebKit.
