Is there innovation in non-virtualized non-containerized shared hosting?

Question

I read http://adamierymenko.com/ports.html and thought it was interesting. I think there is a lot I need to understand to fully understand it - so be gentle. But I think it is trying to say if you had bear metal, install (a patched?) Linux on that, you could use the built in user permissions to host multiple applications separately, and it would be secure.Is there any providers that provide this sort of hosting? Is this kind of what those old school "shared hosting" PHP-type hosting providers (like Hostgator, for example) are providing? Or is that different. I guess those are more locked down, you can't just run anything, but they normally come with Ruby, PHP, Node and so on.

My understanding of many shared hosting providers is that they effectively 'jail' your ftp access to your specific directory and then probably use permissions in some form to prevent php/ruby/etc accessing out of that directory.
Do shared hosts support node now? I havent used a shared host since I learned PHP, but given the effective difference in how node scripts are ran vs php/RoR/etc, it seems like that would end up complicated
Edit: Quick google answered my last question - shared hosting providers that also support nodejs tend to do so via vps

For future reference I saw Firecracker mentioned in another thread. That seems close to what I am thinking!
