Yes, but the simplicity is in a different level. Especially in nameserver-based designs, which is quite major, namespacing is a matter of using a different name

Yes, but the simplicity is in a different level. Especially in nameserver-based designs, which is quite major, namespacing is a matter of using a different nameserver. The implementation boils down to one syscall that writes to a single uint value in the process struct (which would take, idk, 10 lines in total?).
