I have only been testing Type 3 with scsi_debug (which conveniently
avoids the formatting step).

I doubt we will see any disk drives that support Type 3.  The way the
standard is written, a drive can either do Type 1+2 or Type 1+3.  Type
2+3 is not a possible combination.

In any case.  If you happen to own a Type 3-capable device you format
it exactly like if it had been a Type 2.  I.e. set PINFO=1 and
RTO_REQ=1 in FORMAT UNIT.  sg_format can already do this.
