This does not answer my question related to the sharpening slider.
Is the new value an equivalent or not? Why did it change? I'm not saying is unacceptable, I want to understand the nature of the change and make sure I don't oversharpen the images
"Deal with it"is also not a great answer. I'll have to change quite a few scripts now as those are coordinate dependent.
You do realize that these changes affect the paying customers and their clients, right?
The new default of 40, up from 25, is more sharpening:

I expect this is because camera sensors are much higher density, now, although lenses aren't that much sharper, so the older value wasn't having as much effect as it used to with lower-res sensors.
Here's an online article that says something similar:

As far as the Profile line, no you cannot hide it. It used to be in the Camera Calibration tab. now it's been moved to Basic, since all the new profiles apply to both raw and non-raw (jpg). Like it or not, this is the phonification of desktop software, where people (usually younger than a certain age) just want to do a few clicks.
I have set a few of the profiles as favorites so they show up in the list without having to browse the preview thumbnails of each new "look" to find them.
Adobe does change the UI from time-to-time, and people get new computers with higher-resolution displays from time-to-time. New software features and new computers aren't just for those people who don't pay for software, right? What automation software do you use? Does it allow locating UI elements by name instead of coordinates?
