I tend to think this will make for a lousy user experience given that
interface names will potentially change on the first boot of the newly
installed system. Not really in favor of this.

Proposal: stop using dhcpcd.service, replace with a udev rule that
launches instances of dhcpcd at .service for network devices as they
appear:

  # /etc/udev/rules.d/81-dhcpcd.rules
  ACTION=="add", SUBSYSTEM=="net", ENV{SYSTEMD_WANTS}="dhcpcd@$env{INTERFACE}.service"

This potentially breaks ordering for units on network.target, but we've
never been able to guarantee that anyways using dhcpcd.service.
