I wouldn't mind a toggle switch in settings that requests me to push "Yes" if I place my phone on a wireless charger. If you leave this function off, it just charges (for people who don't mind the risk).

When you connect your iPhone to a new and unrecognized device, it actually asks to whether trust or not trust that device.
If your device is locked, you need to authenticate to trust to said device.

Really, even wireless chargers? That's great.

A wireless charger has no data transfer capability yet, so "no" for now. However if a USB port shows any sign of data transfer capability, it's blocked until you trust it.
Power starvation / observation attacks are passive attacks in a sense. They get their results by observing only.

The article is about a side-channel attack, where you don't transfer any data, but just observe something (in this case power draw from a wireless charger) to get some information.
In these types of attacks, you don't transfer any actual information, but guess something from observation.
There are more exotic attacks [0][1] which exploit the heat computers generate to exfiltrate data or time power starvation attacks.
