Actually, there's a really obvious case where this simply isn't true.

Just imagine you're a MIS person or a developer, doing "ps -eLf" to
see what's going on, and want to kill one thread. Either because you
see that one thread using all CPU, or because you are the developer
and you know what's up.

Those thread ID's are exported trivially.
