OK it is faster as article claims but I want to see the tickets, team composition, how long they work together, team dynamics, assholes blocking PRs vs assholes pushing stuff to trunk „because they know better”. Amount of work that was done and amount of bug reports and anyone can write that their customers are happy. If they worked previously on PRs some numbers how that was going compared to what they do now. For me it is just fluff and I wasted time reading it.
