When you say "Windows-specific variable names", to what are you referring?
The values you list below appear to be constant values, and should have
names associated with them.
In section 2 of [MS-CIFS] and [MS-SMB], we did a great deal of work to make
sure that constant values and their associated names were defined. See, for
example, the definitions for bit values for the Flags and Flags2 fields in
the SMB Header, [MS-CIFS] section 22.214.171.124.
Perhaps I am not understanding the discussion here. What clue am I missing?

> Is the absence of the Windows-specific variable names blocking your development? There may be push back to do so since this is in the normative section of the document. I agree that it seems like a helpful suggestion. Is there an argument I can present on your behalf to show a reason that doing so is required to implement the protocol.
