Basically you can actually do the things you often need to do. Conversely on MacOS if you need to do any of those things your only option is to use Finder which really sucks because you then have navigate to wherever you were in the app
And of course you can set the icon size in Windows file dialogs, something you can't do in MacOS file open/save dialog
So in this case, thank god the engineering mindset won out in Windows, at least for this particular feature. Whatever UX designer on MacOS decided to neuter the file dialogs failed UX class apparently and chose based on some random airfairy idea then users actually getting work done.
