Deprecation warning - deprecations need to deprecated

I don’t know about you, but the deprecation warnings when Plone starts up are getting kind of annoying. Here’s the trimmed down version:

2006-09-11 22:44:25 WARNING Init Class Products.ATContentTypes.content.base.ATCTFolderMixin has a security declaration for nonexistent method 'manage_copyObjects' 2006-09-11 22:44:28 WARNING Plone Deprecation Warning The CMFPlone.MemberData class will be removed in Plone 3.0 2006-09-11 22:44:30 WARNING Plone Deprecation Warning CustomizationPolicies are deprecated and will be removed in Plone 3.0. Please use GenericSetup extension profiles instead. 2006-09-11 22:44:30 WARNING Plone Deprecation Warning registerSetupWidget is deprecated and will be removed in Plone 3.0. 2006-09-11 22:44:30 WARNING Plone Deprecation Warning registerSetupWidget is deprecated and will be removed in Plone 3.0. 2006-09-11 22:44:37 WARNING Plone Deprecation Warning CustomizationPolicies are deprecated and will be removed in Plone 3.0. Please use GenericSetup extension profiles instead. 2006-09-11 22:44:38 WARNING Plone Deprecation Warning registerSetupWidget is deprecated and will be removed in Plone 3.0. .. and a few removed (see below)

Further if you set etc/zope.conf to only show errors and above you still get a few:

Use the Python logging module instead. LOG('Marshall', level, msg)

So first off, how do we supress these errors that are presumably using the logging module?

Secondly how about using the power of the internet and making a web page that describes what to do. I don’t know what marking the class actually means, but I’m sure if someone put up a page explaining it, and a link we could figure it out eg:

Products.kupu.plone.plonelibrarytool.PloneKupuLibraryTool.manage_afterAdd is deprecated see http://blogs.nuxeo.com/sections/blogs/florent_guillaume/2005_11_08_events-in-zope-2-9

(which btw the way is a useful blog post on the subject, hiding down there in the Google results)

Do I really need to see all this? Can we put this into a unit test that will do something like test –show-deprecations? Deprecation warnings in products I develop are useful, but I fear, I like most or just ignoring these logs. If that’s the case we are losing the battle.
