applied, but with a followup reducing the default timeout to 1
second, which should be still high enough for most people, as TCP
needs roughly 1.5 time of the Round Trip Time for connection setup,
So, with 1 second timeout we're still good for connections with 660ms
latency in-between.

Users can always increase it if required in their environment.

Thanks a lot!
