Thank you Robert and Tels. Yes, Tels's comment sounds plausible as a representative real user who expects high availability. I'm sorry to repeat myself, but this feature is for HA, so libpq should attempt to connect to the next host when it fails to establish a connection.
Who can conclude this? I don't think that no feedback from beta users means satisfaction with the current behavior.
Regards
