[Zope-CMF] [dev] Should portal_setup be registered as utility?

[yuppie]

Hi!


CMFDefault registers portal_setup as utility. Some code in CMF depends 
on that.

Plone doesn't doesn't register portal_setup as utility:
http://dev.plone.org/plone/changeset/18763

That causes some trouble in Plone:
http://dev.plone.org/plone/ticket/7714

The same issue was reported as CMF bug:
https://bugs.launchpad.net/zope-cmf/+bug/263525

Due to a misunderstanding the CMF bug was marked as 'Won't Fix'.


Questions: Is there a good reason why Plone doesn't register 
portal_setup as utility? Does the same reason apply to CMFDefault? Do we 
have to support registered and not registered portal_setup tools?


Cheers,
