Okay, let me try again.

I understand that a client SHOULD use CAPABILITIES to determine if the
extension is supported. A client should only use MODE STREAM if it's
concerned about old implementations. However, that's not my point.

Let me ask the same question in two ways:

Version 1: can an implementation conforming to your specification
NOT implement the MODE STREAM command?

Version 2: is the following allowed with a conforming server?

    [C] CAPABILITIES
    [S] 101 Capability list:
    [S] VERSION 2 
    [S] READER LISTGROUP 
    [S] LIST ACTIVE NEWSGROUPS
    [S] STREAMING
    [S] .
    [C] MODE STREAM
    [S] 501 Unknown mode STREAM

If the answer to both of them is "no", then you need my changes.

If the answer to both of them is "yes", then you badly need to rephrase
that text, because I thought it was a mandatory command.

If the answer to one is "yes" and the other is "no", somebody is *really*
confused.
