The surprise is not ameliorated by the availability of a command
toggling some visibility.  The novice user caught by surprise will not
think "Oh, I should have called vis-mode-disable in order not get

And then he will get aware of it.

Strange.  I think I read the contention several times that it would

Sure, but if we have an inconsistency there, the solution is to fix it
instead of providing a command nobody would ever think of using,
because it only uglifies the current buffer and does not cause
anything different to be yanked to the destination buffer.

It won't do a harm to have such a mode for debugging info files and
their display, and other invisibility matters, but it would be an
illusion to think that it would be of major interest to novices, or
help them much.
