They already announced it. Here they only mention the special case where it does not apply:

> In addition to the advanced flow we’re building free, limited distribution accounts for students and hobbyists. This allows you to share apps with a small group (up to 20 devices) without needing to provide a government-issued ID or pay a registration fee.

i.e. Government-issued ID and fees are needed for more than 20 devices, e,g, every app on F-Droid

Note that the OP is about side loading, i.e. installing apps from non-Play Store sources and thereby circumventing developer verification.
