Any objections/comments on axing out old ATA stack?

Hi.

Since FreeBSD 9.0 we are successfully running on the new CAM-based ATA 
stack, using only some controller drivers of old ata(4) by having 
`options ATA_CAM` enabled in all kernels by default. I have a wish to 
drop non-ATA_CAM ata(4) code, unused since that time from the head 
branch to allow further ATA code cleanup.

Does any one here still uses legacy ATA stack (kernel explicitly built 
without `options ATA_CAM`) for some reason, for example as workaround 
for some regression? Does anybody have good ideas why we should not drop 
it now?
