We already have the "visibility" key. Why do we need
another (much obscurer) way to achieve the same thing?

I hate that:

  While you might have the feeling that it were deprecated,
  'ZSQLMethods' still use part of the old style initialization
  (they have an "initialize" but still use "methods", "__ac_permissions__"
  and "__module_aliases__").

  And I occationally recommend these old style facilities.

  Having a warning period of 5 days (post on Oct 27; code freeze Nov 1)
  seems very short.

What about removing the code for Zope 2.10?
