It's certainly an improvement, but in the end it ends up like the "type in your password to continue installation".

If an app is not notarized, you can right click and open it.

Do either of these enough, and it becomes automatic. Back in the day, on Windows, pretty much everything out of the box had to be installed "as admin". Even the most mundane apps required admin. Folks just routinely simply logged in as "admin", giving every random app privilege, make the limitation effectively pointless.

Many apps on the Mac require an admin to install them. It's not universal, like it seemed to be on Windows, but many apps require admin. It's not a leap to blindly right click on a new downloaded installer, and type in your password to install it. Or "<App> wants to access removable media" "OK!"

We're conditioned to just click through these warnings because, honestly, we just want the software, and we just want it to work. We don't want to interview everything as a hostile party.
