Two problems. First, implementation. New devices would be required
that make use of disconnect. If history is any teacher these devices
would be few without brain-damage. The other problem is backward
compatibility. Ever take your high-speed scsi buss and disable
disconnect for ONE slow device? Of course this is all speculation on
my part, since non-such beast currently exists.
The last thing I'd point out is this:
There isn't often one solution for all problems, (other than perhaps,
not attempting to solve it...) when someone suggests otherwise they are
likely either selling you something, or badly miss-informed. This old
argument about SCSI VS IDE is a no-brainer for me.
The SCSI implementation in Linux is cleaner/more_default_case than the
emulation thing. SCSI devices tend to be in a higher class when
compared to their IDE counterparts, more cache, etc.
If you cannot, in your mind, justify the extra expense of a SCSI based
system, then there is a mass-marked solution, IDE/ATAPI.
