The doc and Commentary should reflect the fact that it has been
declared "obsolete".  That's the point.

Strawman, again.  No one suggested that you remove any feature.

Read the bug report.  It's about the doc (including Commentary). 

When you deprecate something, the doc for it should state that it
is deprecated.  Everywhere.

That the doc was not brought up to date about this as soon as
the status changed to deprecated was a doc bug 4 releases ago.
The bug is still there.

Emacs is the self-documenting editor.  It should tell users
about itself accurately.
