You can still side-load signed apps. It's a similar limitation to macOS which won't let you run apps that Apple hasn't signed without command line or control panel shenanigans. Compared to iOS, Android still has the advantage of installing your own full browser (like Firefox) with full-fat ad blocking (uBlock Origin, not Lite). iOS is Safari-only right now though, in theory, some alternative engines may be available in Europe later.
If they need to be signed by Google, that's not side loading by definition; it's using an alternate Google channel.
