Nope. For some (IMO insane) reason, the devs of dump decided not to
support the most proven backup system I've been using for 45 years.

I don't understand the decision but attempting to get it corrected is
hopeless.  

Use tar. It's not as flexible but it's your only option.

Note that you can still make UFS filesystems.
