IIRC, this little byte was the first big stumbling stone on the first  
day of the first ROHC interop -- half of the implementations had it  
and the other half didn't.
The decision to always include this byte was made on the afternoon of  
that day, carried forward in all ROHC implementations since, and  
finally recorded in RFC 4815.
