No, not that.

The point of running client / server (== two borg processes talking via
ssh to each other) is that you have an agent on the server.

Thus, repository operations are local the the server side agent.

That speeds up:
- repo check (local operation)
- starting a transaction (does not need to copy repo index over network
fs, but can do it locally)
- likely also other operations, because the server can do repo fs access
and just deliver the result - instead of the client doing that over
network fs in a likely less efficient way.

Also, depending on your network filesystem:
- seeks and partial reads will work (they also work for a normal network
fs, but likely not for some of the cloud-backed fs)
