Taking the view that the command is mandatory but discouraged, the
following would satisfy me:

> "2.3. MODE STREAM Command

>      Historically this command was used by a client to discover if a
>      server supported the CHECK and TAKETHIS commands.  This command is
>      deprecated in favor of the CAPABILITIES discovery command and is

s/documented/provided/

>      New clients SHOULD use the CAPABILITIES command to check a server
>      for support of the STREAMING extension but MAY implement and use

s/implement and use/use/

["Implement" is, to me, what a server does.]

>      Servers SHOULD accept the MODE STREAM command for backwards
>      compatibility with legacy clients which don't use the CAPABILITIES
>      discovery command.

s/SHOULD/MUST/, since it's required for this version.

s/will be removed from subsequent versions/may be removed from a future
version/, since we don't know what issues will drive future versions.

s/and the MODE STREAM command//, since it's mandatory.
