So it's an error about existing *state* of the identity management
system, not an error of the service-add operation itself or error
about the result of that operation. IOW, the code tries to be smarter
than necessary, hitting users who attempt to do things right,
precreating host records. Plus it's an error about related object,
not the object being manipulated / created which in itself is
suspicious.

I guess you are then talking about not having that check in the
host-add operation, not service-add:

        # ipa host-add --random client56.example.test
        ipa: ERROR: Host does not have corresponding DNS A/AAAA record

Because to face the error during service-add, the user must already
have overriden the error for the host itself.

So how about:

        No DNS check / error in host-add when --random is used.
        No DNS check / error in service-add at all.
