This seems to be exactly what I was looking for, thank you! I see fallback specifically mentioned under the reboot option in the man page now (although it doesn't seem to appear in the dhcpcd.conf man page). I had the idea of a timeout stuck in my head and overlooked it.

I synced the text here:

    If that's the case why bother with a static profile? dhcpcd will poll ad
    infinitum to get a DHCP lease by default.


The clients are relatively portable and get pulled on and off networks. They can end up somewhere without a dhcp server or just need to be reachable in an ad-hoc way, and the fallback is handy for that.

Maybe consider IPv4LL and mDNS instead to solve that?
