Looking into it deeper I guess that any changes should be made in
main.py - either in wsgibase() or the beginning of serve_controller()
as some defaulting is already carried out in these methods ('init'
application, 'default' controller, 'index' action, default view name).Are the new defaults fixed or configurable? If configurable then absence of values can be taken as "existing" behaviour. But where to get the defaults from? How about a new something.py in the app folder that is processed when an application receives a request (like db.py) but before models and controllers are processed? Could this same file have a role to play managing plugins (see other thread "T2 almost here")?
