I agree with everything you said here. Most of it transfers to macOS as well. Readability took less of a hit, thankfully.

Some of the work appears so shoddy that I wonder if it was done by code mods or something. The Passwords app on macOS looks bizarrely cluttered and cramped, with all kinds of bad artifacts when you resize the window. I know it's a beta, but it's so bad that I really wonder if a human looked at it for more than a minute before they shipped it out.
