Nowadays gentoo already offers binary packages natively, if the user wants them ( https://wiki.gentoo.org/wiki/Gentoo_Binary_Host_Quickstart ). Default is sill to compile locally. But for large packages like libreoffice or browsers the binary packages are nice.

But i can see the benefit for new users in getting sth pre configured. For this to be long term usefull though,the documentation is crucial. Maybe just offering the guide to this specific install or how it differs from the standard install manual, like sakakis install guide (sadly defunct).

seems so, and the steamdeck too I think macs also have sth like this.
