base_controller_class is always loaded / required, even with lazy loading

[tight]

👋

I noticed that when starting my app in development (with lazy loading), base_controller_class is always loaded (which in turns loads a bunch of files from my app) and I would like to avoid that, since it increases app boot time
There's a specific piece of code to load the base_controller_class here added in this old commit (see comment).
Also, I changed mission_controll-jobs' dummy app in tests to use a specific class and commented the code above, everything still works, tests pass, no loading issue
So, I'm wondering if this piece of code still make sense, and if it can be removed?
