BTW in a network set up like my own, the place where the MAC would be
relevant is in the DHCP server (here, the router) because that is how
the IP number is assigned. An unassigned MAC will get given an IP

machines on the LAN would not recognise it. (Although the router can
hand out IP numbers, it doesn't run a nameserver.)
If you do something strange on your network, the assumption is that
you're responsible for updating it for new machines. It's not
something that needs to be in a general guide.
I agree with that sentiment. But what is strange about my setup?
Perhaps you can help me find a less idiosyncratic way.
Condition #1: All devices at home must be addressable by name.
Condition #2: Several devices cannot have a static IP address assigned.
For example, this PC is 192.168.1.17 at home. Currently it is 172.20.5.105;
last night it was 10.0.27.15.
So at home, all the IP addresses are assigned by the router using the
devices' MACs. The computers use /etc/hosts to look up other devices.
The non-"computers" use the router's IP address for their configuration.
What would you change?
Buy or build a router with a caching name server that integrates with
the DHCP server. Configure the LAN devices to use DHCP. Set DHCP fixed
leases on the router for devices that require a static IP.
