smyruI have a feeling that Google aims at using this sideloading scare / FUD to counter alternative stores required by regulators and courts.

"Google used to do very little curation of the Play Store[…] Years ago, you could publish actual exploits in the official store to gain root access on phones, but now there are multiple reviews and detection mechanisms to reduce the prevalence of malware and banned content. While the Play Store is still not perfect, Google claims apps sideloaded from outside its store are 50 times more likely to contain malware."
