I don't think so:

1.) If you start rendering the default view before the controller has 
finished you need extra code to abort the rendering if necessary. E.g. a 
tal:condition that wraps the whole template.

2.) A cleaner separation of controller calls and view rendering makes 
the code simpler and therefore easier to write and maintain.

3.) Rendering useless views wastes resources.
