Literally everyone? I’ve been a software engineer for ten years. My company doesn’t use it, and no company I’ve worked for has. I guess they are not part of “literally everyone?”
Explain to me how GitHub working on one product feature (releases) has no impact on how much they can work on others. Apparently in your rich enterprise software career you’ve found that resources and time are limitless? Or maybe you think it’s trivial for a platform like GitHub to change their UI.
This smacks of lots junior software engineers I’ve worked with who think problems are simple and solutions are easy because they’ve never actually DONE anything. I get that you’re very convinced that this is easy and cost less but it’s pretty clear to me you have no idea what you’re talking about.
