There are 7 types of namespaces, I don't see it mentioned which types they use. Mount namespaces are not a big deal to use, as long as you freely bind-mount from /dev and /sys whatever your software might need. The effect is mostly protecting your home directory against both reading and modification and isolating your system installations against version and configuration conflicts. Uid namespaces are really challenging if you try to make some complex software system work. They give a lot of isolation from the host system, some would say also new risks that the isolation has unexpected privilege escalations.
