Choking signal to save lives...

That has already happened with first aid training here. Although the two breaths and thirty compressions is the recommendation, it is now acceptable to leave out the breaths as there is no evidence to show the outcome to be different.

Outcomes are actually marginally better if you don't bother with the rescue breathing.
Rescue breathing causes insufflation of the stomache, which in turn increases the risks of vomiting and aspiration. Given that the cardiac output during CPR is only about 25% of what it would be normally, there is sufficient air moved with compressions. At least until such time as someone is able to provide a definitive airway.
The rescue breathing now is simply out of habit. Cultural inertia. It'll be phased out completely soon enough.
It's sort of like spinal precautions for trauma patients. Backboards and C-Collars don't actually help anybody. But the lawyers expect them to be used, so they're used.

As to the Heimlich manoeuvre, it is now out too.

That's still the heimlich, they just don't call it by that name anymore. Maybe Dr Heimlich wanted royalties.
