It would be relevant to whether or not it should be set to 3 by default
in the kernel without explicit configuration, but there's no proposal to
do that. Debian has to pick a trade-off beyond security and a tiny
roadblock for developers. It's not always the case though.

In Android, there's userspace integration allowing it to be toggled by
the Android Debugging Bridge shell user so profiling tools are being
taught to automatically toggle it. Enabling ADB and then using it for
profiling is an implicit opt-in.
