Not all OS9 disks need to be bootable.  I got software distributions
(like the C compiler) on OS9 formated disks with no OS on them.

See above.  :-)

People believed that at one time, but it is not necessarily true.
I think the 6809 has an HCF instruction.  I agree that there should
be a way to look at the data on a disk and tell what kind of disk
it is.  But then, just telling the difference between OS9 and DECB
is only useful if you know for a fact that you have no other format
flopies laying around.
