As someone running a software product team, we've made the decision to get as close to the developer process as possible with our product management tools. We've recently started doing everything in Github using Github projects, which honestly is really usable. It's kind of put me in a mindset where I'm not sure why I would ever pay for a separate product management tool as I can do most of my critical things with Github + Markup + our design stack (Figma, etc).
Obviously there's a market for this as I think people are still chasing potential efficiency gains in making tools that are easy/fast/effective in organizing work, but as a product leader I don't see anything here that compels me to leave Github.
