One could argue that if an application really wants to connect to a peer, it should probably handle failures and retries.
But for unaware (basic ?) applications, the 3 -> 1 change reduced by a 3 factor the timeout. So a transient network failure has now more chance to impact them.
Not all applications run inside a browser or under human control...
