Actually I agree with you completely. The 5x improvement is what it takes BigCo management to notice you. However startups are getting the 5x advantage all over the place. Nimble platforms plus smarter people plus stripped down organizations give you your 5x. I have been inclined to think for quite a while that a good IDE / compiler combination would achieve a lot with a language Python. (I've been doing my Python development with an ordinary editor.) Python 3 allows type specification, but doesnt do anything with it. Have the IDE get feedback from the execution profile to advise the programmer on possible type errors. Testing tools: I would like a tool that can read a method and some annotation to generate a set of unit tests. Given your list I think it results in way more than 50% improvement.
