when majority of people saying “Photoshop has this, we should do this as well” are not actually saying GIMP should create a total carbon-copy

And I see with my own eyes how some people are saying exactly that. Sometimes they wrap it into something like “photoshop is intuitive industry standard that takes zero seconds to learn and everyone is born with perfect understanding of it, and everything that isn’t that is an affront to god and actively violates all my senses”. I’m paraphrasing a bit.
