I may well be wildly wrong, but that looked to me like the domains
condition on a typical dnslookup router instance ...

... would correspond to a router like

dnslookup:
driver = dnslookup
domains = ! +local_domains
...etc...

... which makes sense (to me; YMMV)

What struck me as more interesting was what came next ...

... shouldn't that last one be 'yes'? As indeed it was in the 'corrected'
version:-
