Systematic error in Help files of RTW re -outbuffer?

In the Common Parameters section of Help mention of -outbuffer seems
to be systematically omitted:

e.g. type
get-help get-command -full
and look at:

<CommonParameters>
This cmdlet supports the common parameters: -Verbose, -Debug,
-ErrorAction, -ErrorVariable, and -OutVariable. For more
information,
type, "get-help about_commonparameters".

I haven't checked every help file but the omission of any mention of
-outbuffer is present in at least several of them.

Cf
(get-command get-command).definition
and similar commands where -outbuffer is routinely mentioned.
