Bear in mind that there is a difference between getting the wrapper 
itself, and getting the value to catalogue for a particular *attribute* 
of the wrapper (e.g. allowedRolesAndUsers).

The CatalogTool subclass in Plone solves the former. plone.indexer uses 
the hook it puts in place to solve the latter.

I think at a minimum, CMF should just make the whole wrapper swappable 
by looking it up as an adapter. Then people could choose to use 
plone.indexer if they so needed (we'd obviously need to change 
plone.indexer to provide an appropriate adapter based on a CMF interface 
rather than a Plone one, and then deprecate the Plone version). For 
smaller applications, it may just be unnecessary complexity.
