Let me suggest a possible solution: Maxime very sensibly wants to minimize the attack surface of a basic, default, installation of the system. The main argument against this is that it would mean that casual installers would find that they couldn't run e.g. Linux binaries on a NetBSD/amd64 installation without making some extra incantations, ones that they naturally don't know about.
What if the default were the safe mode that Maxime recommends, and the installer helpfully had a stage that said something like "Your platform has the ability of supporting one or more emulations for your convenience. Please select from the following menu which you would like to enable. (You may, of course, change this later; see 'man emul' after installing to learn more about this.)"...? -tih -- Most people who graduate with CS degrees don't understand the significance of Lisp.
