Right, but if I do add the /1, consumers that haven't upgraded will break 
even though nothing substantive has changed.

If there were something substantively different between 5451 and bis, so 
that consumers had to change to consume something other than the version 
number, I would probably be OK with the slash.  But in this case, the 
slash doesn't solve any problem I can see, and is likely to cause some 
interop issues.
