This is actually necessary. If you don't start a real DHCP daemon on
boot, then you won't renew your lease and the DHCP server may give the
IP to someone else.

Your lease should still be valid when you re-launch DHCP, so you can
rely on getting the same IP. You could probably even configure dhcpcd to
specifically request the correct IP.

None of these are good solutions.

We must not stop network on shutdown. We can quit dhcpcd without
releasing the lease or shutting down the network. If this is not
possible with systemd, then something is very wrong.
