OK, I was wondering this because qemu-user-static still pulls in the 
binfmt-support

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following additional packages will be installed:
  binfmt-support
The following NEW packages will be installed:
  binfmt-support qemu-user-static
0 upgraded, 2 newly installed, 0 to remove and 2 not upgraded.

Other distributions such as Fedora have already switched to systemd-binfmt.
