Once again, please do NOT enable this by default, I didn't agree to
that.  This feature should remain disabled by default for some time,
until we have enough information to discuss whether it should be
turned on by default.  As discussed and agreed during its development.

"One of the recently deleted frames" sounds like Emacs arbitrarily
decides which one.  Which is not  what you wanted to say, surely.

This doesn't say how to disable the feature.

I think Gregory didn't like the disappearing item, and preferred it to
be visible at all times, even if disabled.
