This sounds like a good reason not to have the command at all.

If we decide not to install that part of the patch, my request is a
moot point, but as long as the command is described in the manual,
please add the mutual cross-references between it and `handle'.

Sounds convincing to me, assuming that auto-negotiated settings never
lie about the support and seldom have bugs that make them not useful.
I'm not in a position to say whether this is true, since I don't have
enough experience with debugging remote targets.
