When you find an app, F-Droid 2.0 will make the installation process easier. Google has long put up roadblocks for sideloaded apps, citing the security implications. This is also the rationale behind its upcoming developer verification system. For now at least, apps will be easier to install from F-Droid thanks to the use of Google’s pre-approval API.

That answers my question if those smoother installs already account for Google's insistence in making "sideloading" way more annoying. They do not.
