[Zope-CMF] [dev] CMFSetup backwards compatibility policy

[yuppie]

Hi!


CMFSetup is fast changing code and maintaining full backwards 
compatibility is a pain, slowing down development.

I don't think we should try to maintain code compatibility on HEAD. All 
we should promise is that imports of old profiles work and that we don't 
break the persistent SetupTool.

I believe we have already a policy like that, just want to make this 
more explicit and give people a chance to correct me.


Right now this means (on HEAD):

- I'll move factory.py around and don't plan backwards compatibility for 
addConfiguredSiteForm/addConfiguredSite imports.

- I'd like to remove the BBB code in typeinfo.py.


Any comments?


Cheers,
