They were happy that someone finally made a decision, and freed them from the burden of fruitless repeated deliberation.
Not in the sense of "This is how long that will take me" (because who cares about someone else's time?), but in "Of the 3 things you requested, which 1 is your must-have?"
Often this is approximated via design/dev team pushback, but it's easier just to be explicit about it: i.e. everyone gets X change request tokens.
This is also the difference between a supremely dysfunctional and an OK-ish standards committee, the classic Home of Bikeshedding.
LLMs however... they give part of this power to lower levels as well. After all, what is an LLM other than the condensed knowledge of humanity? (Partially /s)
Apple has the benefit of massive cash-flow and, as a result, hiring many competent designers who draw and create to a specification. The specification could be created by another team of senior designers that are paid handsomely to deal with the gruelling task of defining a corporate identity.
This is similar to how major feature cartoons, which typically require variations of an image to be drawn over and over again, are typically animated by more than one person.
I.e. Apple has the money. They can do better than having one extremely hand-cramped illustrator crank out silhouette-style icons.
But they haven’t. The latest Mac OS is atrocious. Glass? Are they literally trying to mimic 2006’s Compiz?
What this did teach me was to create very efficient workflows. I had all the Inkscape keystrokes memorized and found out they had an API that allowed me to create some level of automation (things like batch conversations IIRC). I kept certain symbols as separate base/template images so I could quickly swap things in and out. I had separate color files with swatches of various color themes, all in hexadecimal. Since I was and am fundamentally a software engineer, I used those engineering processes and principles to make it more like a typical software project than just a collection of images.
