It is, or at least its "do minimal logging of DHCP interactions,
considered to be generally useful." Setting --log-dhcp produces much
more information about each DHCP transaction, suitable for debugging.
The minimal logging does assume that a sane dnsmasq installation is not
doing multiple DHCP transactions per second. I think that's a reasonable
assumption.

You can direct all dnsmasq logging to another file with

--log-facility=/path/to/file

or remain in blissful ignorance of your broken clients with

--log-facility=/dev/null

Cheers,
