It looks nicer + you can just use the scroll wheel. A lot of the UI affordances lost over the last decade or two are unfortunate, but complaints about scroll bars seem to be purely baby duck syndrome.
Obviously not, but you also shouldn't expect the whole world to be designed around your needs. If you have difficulty using the expected input method, you should use alternatives with the same functionality, not expect others to redesign their apps in your preferred way.
Design for the best accessibility first and foremost, then try and make things look "prettier".
Disabilities can affect anyone at any time and shouldn't be an afterthought.
Most of the terrible designs and accessibility problems stem from software going out its way to write custom controls or force controls to look and behave in a non-default way. It's not an afterthought--people are deliberately adding code to make their software worse.
You design a clear, visible, distinctive scroll bar and buttons? Boom, you've catered to everyone with bad vision (for any reason: from blindness to eye surgery), reduced motor skills (for any reason: from arthritis to old age to hand injuries), non-technical users (so they don't have to hunt around the interface hoping to discover hidden features).
And this goes for everything in software.
Disability is a spectrum, and you yourself will be disabled in one way or another, multiple times, during the course of your life. Be it from old age, surgeries, injuries, strain from sport or mundane tasks like holding a baby.

It is thr toolkit builder's job.
As an application developer you should not have to
I don't think anyone is expecting that. What's reasonable to expect is that these things are configurable so people can have a UI that works for them.
And no, trying to scroll every control just to find this out is not my ideal of usability and comfort.
We know the exact temperature and humidity outside, we have logs of the exact times that our smart lights turned on and off. Our watches tell us our heart rate throughout the day and even its variability. Our phones monitor how much we use them, and in which apps, and report back weekly. When I had outlook in the office, it would summarize how much time I spent in meetings, seemingly to increase my stress level one more notch.
The lack of a scroll bar returns mystery, but even more, it brings us back to a simpler time when we weren't overloaded by information such as "how much is left of this text?" or "is there a button hidden somewhere on this page that allows me to complete my task, or is the app just broken?"
These are the sorts of small joys that we miss in the Information Age.
It is an enabler of information overload, not a solution or respite.

that information can be conveyed with a 1-pixel wide bar with proper color contrast, not requiring a waste of the whole scrollbar's width
Maybe this bright idea that information and control are separate things can inspire the future gen of UI designers to actually make this a reality
I was searching for a way to make Mac scrollbars wider literally yesterday. It's 100% a real problem.
On my desktops I've got more screen width than any of my open windows know what to do with, and they still want to skimp on scroll bar width. I can understand with mobile, but mobile design decisions are crowding out desktop usability. It's lazy and cheap but the market is monopolised enough that the approaching horizon can only look "no worse" at best.
"Beauty is in the eye of the beholder". My work laptop does not have a "scroll wheel". There is a posibility to scroll using the touch pad but it is undocumented and hit or miss.
