Thank you Petr,
indeed I wouldn't mind at all to add a `,forever` in these dhcp-host
lines if it automatically added them to DNS without having to boot them.
Or to use a `dhcp-range=....,some-flag` syntax.
Fortunately a script that converts from dhcp-hosts to addn-hosts was
rather easy to implement, so I'm happily using that.
Thank you all!

I think you can use addn-hosts for name<=>IP address mapping and use
dhcp-hostsfile just for mac address assignment to existing pair. But it
prevents ability to create one file the other one, because primary data
are split into two files. I guess creation of addn-hosts from dhcp-hosts
by a script is the best solution available. I don't know about any way
just with one line per host.
Perhaps a flag could be added to dhcp-range, requesting also addition of
dhcp-hosts to static dns. Would it help if those hosts were assigned
infinite TTL to add permanent hostnames for them, similar to addn-hosts
record? I guess it would not hurt having permanent names on permanent
