When you disable the DNS-server via

It's at least a documentation bug. I think the reasoning behind the
behaviour is that setting port=0 disables all the DNS functionality,
which can be useful for its own sake, but also saves machine
resources; no memory is allocated for cache and all the configuration
infrastructure for DNS is not initialised, hence /etc/hosts doesn't
get read.
It would be trivial to remove half a dozen "if (port != 0) { }"
lines from the code, and have all of the DNS stuff still live apart
from actually listening on port 53, but that's not necessarily an
improvement. There's not increase in functionality, since the same
behaviour can be configured simply by adding the the addresses to the
dhcp-host lines and that works with the existing code even when port=0
is set.
My feeling is that the best fix to this is a heads-up in the man page,
but I'm happy to entertain arguments to the contrary.
I believe that /etc/hosts is generic database which is used for name<->IP
mapping wherever it's needed. This should imho include static DHCP
configuration.
I also believe that the resources part is not important nowadays.
