+1. My thinking of this has been:

a. It's Apple-specific, let's hide it
b. ...But Macs are important too, let's not hide it (that's where I
submitted the file-id patch which adds an Apple-specific flag to the SMB
server).
c. ...But their version of the protocol is not documented and subject to
change without notice, and Microsoft's version currently is documented
and supported, so let's keep the main SMB code adhering to the
documented protocol version and (try to) hide undocumented dialects.

Just my 2c...
