ok, so extra lines for .10, 16-32.172, 168.192  - an extra 18 lines in
total.   And an update to luci to remove the bogus priv tick box?

It doesn't. nslookups for my local boxes on 192.168.n.x configured
either as known hosts or as dhcp leases work fine.  I'd like to think I
would have noticed if it didn't.

May I suggest that is a 'special use' case and requires sensible, extra
configuration just like many other uses.  I'm suggesting an Internet
friendly default, admittedly one that requires extra effort to disable
if a use case requires.
