I disagree.  With 2-3 options max to set once instead of creating a 
bunch of layer nodes, how can't this be helpful ?

Isn't the opposite : with all layer nodes having their options, the 
implementer has to go to see what was created more times than if you 
have 2-3 options to set once.  And it's also longer to do so.

No need to.  It would be a new driver with its own options, so a second 
way to do things.  Like all widgets created in GeoPrisma: they are all 
unique, customized to do one or more thing and are all ok to use. 

To keep in mind : my goal is to make it shorter, faster to create and 
simpler for the implementers to create the config file, and 'automatism' 
seems a good approach.

Even if I'm already 'sold' to the new idea, I totally agree that we 
could skip it before 1.0 and concentrate on what we have.  What we have 
right now is still usable and will continue to be supported.

Any ideas ?
