On the other hand, does some kind of history remain? Permanently removing something can also be an issue, i.e. a problem user could remove their own inappropriate posts from view whenever a ban or demotion request came up, so they couldn't be cited for consideration anymore. Also, with a regular talk page, vandalism could be removed by any user rather than requiring admin activity, as it usually can be, so a wall would also lose that functionality. Having it as a normal editable talk pages with a history and everything actually handled all of this perfectly in the first place.
