Bear in mind that collective.lead itself will be using zope.sqlalchemy 
for transaction integration, and focus on providing a pattern for 
registering and accessing database utilities. If Grok needs/wants such a 
pattern, collective.lead should continue to be a viable solution. If it 
wants/needs its own way of looking up and managing database connections, 
then obviously not.
