This is a platform feature that asks forgiveness for PROGMEM misuse: it adds a handler such that incorrectly used PROGMEM will work without crashing, just really, *really* inefficiently. Given that most of our real-world use cases for PROGMEM strings are relatively infrequent text calls, we can err on the side of developer convenience and address performance problems if and when they arise.
