Deprecate Ban module

@andypost, thanks for starting the issue. If you like, I will setup the issues for the other planned removals.

@quietone thank you, makes sense

Situation here seems a bit different/more complicated than some other core removals as there are multiple alternative modules and additions. We use it in combination with https://www.drupal.org/project/perimeter → and https://www.drupal.org/project/auto_unban → , which also overlaps with autoban and advban.

Should we consider to deprecate ban in favor of an existing contrib project like advban? Or do the opposite, and merge those additional features into the ban contrib project and attempt to establish a new 2.x release branch of that as the canonical solution for some of these ban features?

I'll ping a few of the current maintainers of those projects on slack.

That would definitely be my personal favourite!
