Breakpoints cannot replay. They can pause and continue playing.

The inability to examine a time series of data after-the-fact and resume from any point makes this approach significantly, significantly worse. Like, I've done it just as you have, and I'd under no circumstances go back. It's so bad that I've basically built action-pattern systems in other languages (before using Redux, actually).

Functional tooling and composition with managed side effects is fucking awesome and doing otherwise verges on footgunning if it doesn't camp right out there.

I guess you must be having a whole different set of problems than me. I also use Redux, have not found time travel to be a boost to my productivity. I choose Redux because of the simplicity around state management, and having it all centralised in a store is a nice pattern. (Don't really get other commenters claiming that this isn't new - I don't see the relevance).
