[Libguestfs] Status of R/W UFS

Is r/w to a UFS partition using 'guestmount' still an impossibility?  
 From everything I've found, it seems to be something that is not 
possible at the moment.  I was just wondering if that has changed or if 
there are plans to change that?

Here is the issue I'm experiencing:

~# guestmount --rw -a ${disk_path}/${disk_name} -m /dev/sda4 
/tmp/freebsd-master
libguestfs: error: mount_options: /dev/vda4 on /: mount: wrong fs type, 
bad option, bad superblock on /dev/vda4,
        missing codepage or helper program, or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so
guestmount: '/dev/sda4' could not be mounted.  Did you mean one of 
these?
         /dev/sda4 (ufs)

I have the output from '-- guestmount --rw -a ${disk_path}/${disk_name} 
--trace --verbose -m /dev/sda4 /tmp/freebsd-master' here:

This appears to be a similar problem to this one, in which I gathered 
that r/w to ufs is not possible:

I get the feeling that this is something I'd need to roll my own kernel 
for, or perhaps just the module?  If anyone could point me in the right 
direction, that'd be awesome.  My apologies for the noise if this is the 
wrong list for this type of question.
