Duh.

That was outdated or misperceived info, obviously.
Both, my current Samsung DVD drive and the LG BD drive
do offer format 0x01 with DVD-RAM.
 Mounted Media:         12h, DVD-RAM
...
READ FORMAT CAPACITIES:
 formatted:             2236704*2048=4580769792
 00h(800):              2236704*2048=4580769792
 00h(800):              2295072*2048=4700307456
 01h(800):              2226976*2048=4560846848
 01h(800):              2217248*2048=4540923904

Last time i checked DVD-RAM formatting was with a
Philips DVD drive that has been replaced by the BD
burner now.
(I should try to revive my old NEC burner and check
 whether i need new glasses or a new brain ...
 probably the latter. Shrug.)

Some observation with the -ssa=none BD-RE media
(so it is good for something):

It still makes a speed difference whether i
use WRITE10 or WRITE12 with streaming bit.

With WRITE10, the drive buffer is filled with
varying amounts under 40 percent:

xorriso : UPDATE : Writing:    1490432s   69.8%   fifo 100%  buf  34%    2.1xB

With WRITE12 and streaming:

xorriso : UPDATE : Writing:     919264s   41.0%   fifo  92%  buf 100%    2.3xB 


Have a nice day :)
