But using my example config, which only allows 1 request per second per user, then wouldn't limit_conn be superfluous? You can't have more than one connection for a single request, surely?
I'll paste the config again here as it got missed off the previous quote:

map $http_user_agent $single_user {
default $binary_remote_addr;
~PaperLiBot 1;
}

limit_req_zone $single_user zone=one:10m rate=1r/s;

...

limit_req zone=one burst=2;
