No, this is not a good analogy at all.

If I don't want to use a certain filesystem, I mount it and copy the 
files over to another filesystem.  What users are interested in are the 
files themselves of course, and the efficiency with which the filesystem 
handles those files.  BK is the efficient filesystem here, but anyone 
should be able to freely copy files over to another filesystem without 
any need for the filesystem internals knowledge.  If the target 
filesystem is 8.3 without lowercase support then so be it and people 
will need to use a separate file to hold the extra details that cannot 
berepresented natively in the target filesystem.  But absolutely 0% of 
the information is lost.

Again, the BK value is in the efficiency and reliability it has to 
handle a tree like the Linux kernel, not in the Linux kernel tree.  It's 
not necessary for you to give away that value in order to provide the 
simple information needed to reconstruct the Linux tree structure as 
people are asking.
