I would work your conf.d/net on the assumption that NO dhcp client is 
installed so dhcp is never tried.

modules="!dhcp"

When using dhcpcd, you only want the net.foo scripts to handle hotplugging of 
wireless interfaces (to start wpa_supplicant).

dhcpcd-5 is designed to configure your entire IPv4 network, including 
interaction with PtP interfaces such as PPP and VPN.
OpenRC-0.5 only ships with a networks script by default to configure the lo 
interface as dhcpcd-5 now handles everything else.
IPv6 is autoconfig anyway (DNS aside).

If the documentation is lacking, please provide patches to it so others benefit 
:)
