Yes.  The reason is similar to making an exception for Connection.
Any agent which parses and understands Connection (i.e. to filter out
named headers) _must_ also understand and parse Transfer-Encoding, as
it determines the message boundary.

Therefore there is nothing to be gained by putting Transfer-Encoding
in Connection.  Mentioning it is always redundant.

This isn't true of the other hop-by-hop headers.
