OK, so let us summarize the options:

a.) wait untit it materialize suddenly in someone's git tree.
b.) add BlockFilter inside BDS
c.) add filter callbacks to block bojs (job_type)
d.) use BlockDriver as filter
e.) use the current BackupInfo unless filters materialize suddenly in someone's 
git tree.

more ideas?
