I haven't tried Fedora 35 yet, but I'd expect it to use
GNOME Software which is not Fedora-specific at all. So, the correct question is probably: "Does Software Center in GNOME 41 behave differently than before in respect to authorization?" I'm not a GNOME Software user, so cannot answer the question.
On CentOS 8 (GNOME 3.32),
gnome-software launches without asking any questions either. But I wouldn't trust it to install anything on the system¹, so didn't check the installation process.

Mainly, because I don't see a clear distinction between regular RPM packages and Flatpaks in it.
