No, I think you were right originally. "Whenever possible" should try

someone would want to configure "use TLS on port 143 if possible, but
not 993".
Depends how long it takes to attempt port 993 and fall back to 143. Some
people _know_ they don't have a server listening on port 993, or they
have a firewall which _drops_ SYN packets instead of rejecting them --
and going straight to port 143 then using STARTTLS is definitely
preferable.
