Those won't be named utilities;  they will be adapters, with
"tool-centric" interfaces.  For code which currently spells the lookup::

  catalog = getToolByName(some_context, 'portal_catalog')

I prefer::

  catalog = ICatalog(some_context)

rather than::

  catalog = getUtility(IGenericTool, 'portal_catalog')

which will permit us to do component-style indirections based on the
type of 'some_context'.
