the problem is that DHCP clients listed in /etc/ethers will not be given IP
addreses specified in /etc/hosts when dnsmasq does not run DNS service
(-p 0), because /etc/hosts is not read in that case.
the workaround is to run DNS at different port (e.g. -p 54), so dnsmasq
reads /etc/hosts and provides IPS configured there do clients from
/etc/ethers, but I believe /etc/hosts should be read even without DNS,
unless explicitly disabled.

Acknowledge on version 2 of "problem description".
I partially understand what the expectations are.
OK, was this enough to get an answer?
is it better to report issues somewhere?

a litle background:
I used dnsmasq on openwrt router using /etc/ethers for machine<>ethernet
address conversion and /etc/hosts for host to IP conversion (for both DHCP
I bought new router with turris (openwrt clone) which uses knot-resolver
(which uses /etc/hosts for local DNS) and runs dnsmasq only as DHCP server
The problem is that while in this scenario dnsmasq does use the ethers table
(I can see that in reservations info), but it does not use hosts table to
assign proper IP addresses for those hosts.
as a workaround I set dnsmasq to run DNS on another port (I'm thinking on
disabling knot-resolvet) so while the DNS is not used, correct IP addresses
I'd like dnsmasq to read /etc/hosts table for DHCP reservations even when
DNS is not used.
... I know I can work around reservations, but I find /etc/ethers and
/etc/hosts good standards to use
