No it's not a bug.
The only configs that are scoped to the engine are load_paths, eager_load_paths, and load_once_paths
It seems that configuration you place inside lib/uhoh/engine.rb will affect your main app's configuration at test/dummy/config/application.rb
I did this in my engine:
And now the main app uses haml for scaffold generation. That seems pretty counterintuitive, since it is within the class of the engine; think that's a bug I should file on Rails?
I was just playing around with this and noticed that the url helper prefixing seems to have changed. I am on Rails 3.1 rc5, but had to downgrade to Arel 2.1.4 to get things launched (which wouldn't seem to make a difference w/r/t this)
