Redmine

I was wondering if is there any design decision behind the limited usage of route/controller resources in Redmine.
I think many models and controllers such as Projects, Issues, Users would benefit from a resource-oriented pattern.

For example, I've just come across the need to redirect to a project url.
Actually the code is full of statements like

link_to 'foo', { :controller => 'projects', :action => 'show', :id => @project.id }

while, with a resourceful architecture, it could be simplified to

link_to 'foo', project_path(@project)

Needless to say this is not the only benefit. Basically it would make the code more efficient, clean and readable.
