Then i have to work a bit more to deserve the title.

Blanking in the meaning of MMC applies only to DVD-RW.
The man page advises growisofs or dd for erasing data on BD-RE,

That's for blanking CD-RW, not for formatting.

UDF tools has a program cdrwtool which can format CD-RW.
Its man page advises
  cdrwtool -d /dev/cdrom -q
This seems to include creation of an UDF filesystem, which one
could later erase like with DVD-RAM.

I fail to understand this statement.
Neither BD-R, nor BD-RE, nor DVD+RW can be blanked.
One can overwrite data on BD-RE and DVD+RW. Rather not on BD-R.
(Well, one can by POW but the "orphanage" would get an overrun
 if this is done with gigabytes of data.)

One "s" too many with "Thomas". :))

Have a nice day :)
