About testing: it's not actually True. Flask is easy to test. Also, Flask makes everything explicit which is less surprising than hidden thread locals. Also, putting things into thread locals somewhere makes explicit request objects totally pointless, because you still depend on threads and can't use Django in an async manner. So it's not a valid good technical argument either. You might like that better, but that's just a subjective opinion.
