Here I'm interested in a use case of subscribers keeping a permanent connection open (24/7), but with negligible amount of messages. So I'm only concerned about price per connection, not price per message.

$0.25 per million connection minutes
That's $1 per 4 million connection minutes.
Since v8.1 (May 2018), Vim has shipped with a built-in terminal. See https://vimhelp.org/terminal.txt.html or type :help terminal for more info.
Why use this? Mainly because it saves you jumping to a separate terminal window. You can also use Vim commands to manipulate a shell session and easily transfer clipboard content between the terminal and files you're working on.
A wrapper for pwgen. Put this in your ~/.bashrc to generate a long & strong password. You can append an optional message to remind yourself of the purpose if you can't immediately transfer it to a credentials repository.
Example usage:
$ hardpass
ZzVMh:u(?ln134`q&PW9rmM0h]rRQ6p-#tv\3I.7
$ hardpass
OXX]k%e1/o-njU0XIK'UT@=\,9OeUGOr
$ hardpass new twitter password
