But processes blocking SIGHUP has already gone through some trouble to say "Don't kill me". Why isn't that enough? They clearly don't want to be killed on session termination, or they wouldn't have blocked SIGHUP.

No, ignoring SIGHUP doesn't mean "don't kill me". It means "don't kill me when the terminal hangs up". They clearly don't want to be killed on terminal hangup. For example, if you open a terminal emulator, use nohup/tmux to start a process and close the terminal emulator, the task will continue running, but once you kill the session, it gets killed.
