Why should someone call an important driver "legacy"?

The sg driver is the official documented method to access any SCSI device and
for this reason, libscg (the SCSI generic library) uses it.
As nobody from the linux kernel folks did ever contact me related to the sg
driver, it is obvious that not supporting sg is a bug.

It is bad practice to replace one driver by another just to cause
incompatibilities instead of enhancing existing software.

and btw. this supposed sg replacement is undocumented.
