Device naming on scbus using isp

I'm wondering about how device names are assigned on scbus, specifically
when using the isp driver. It seems to me that there's potential when an
HBA has access to multiple LUNs that on boot the scbus will have entries
in /dev scrambled compared to the previous run (thus messing up mounts).
My experience so far has been that da0 will be assigned to the first
target scanned, da1 to the second, etc. Is this generally something
countered with device.hints? If a LUN were to go away, but a device hint
pointing to the target:unit remained, would that cause any issues on boot?
