I suppose the question is if Adobe's choices are the optimal ones, or if there's other defensible choices.

I'm an occasional Photoshop and Illustrator user (longtime Fireworks diehard, though, RIP) and while some conventions make sense to me, there's plenty of things that I have to look up tutorials for, even if I've learned them before.

Sometimes different software is different.

Sometimes it's not worth to optimize too farther from the current local optimum. UI designers have a "budget" for weirdness and unfamiliar conventions and must spend it wisely
