It _really_ isn't material to the core capability that localio provides.
localio supporting NFSv3 is beneficial for NFSv3 users (NFSv3 in
containers).

Hammerspace needs localio to work with NFSv3 to assist with its "data
movers" that run on the host (using nfs and nfsd).

Please just remove yourself from the conversation if you cannot make
sense of this.  If you'd like to be involved, put the work in to
understand the code and be professional.
