Why are some devices getting it but not others?

/dev/ttyS? get the sticky bit even though the serial port driver is linked 
into the kernel and this issue is thus irrelevant (at least on amd64).

/dev/watchdog is from the softdog module which can be unloaded but it doesn't 
have the sticky bit.  Why is /dev/watchdog a good device to remove?

/dev/sd* device have the sticky bit set, but they are removed when the 
hardware is removed (EG unplugging a USB flash device).  Why is that?
