Is the Bluetooth 4.2 feature "Cross-Transport Key Generation/Derivation" supported by iOS 8.2?

Question

Bluetooth 4.2 added a nifty feature, defining a way to derive Bluetooth LE pairing information from Bluetooth BR/EDR pairing information and vice versa. When an device uses both types of transport, using this new feature would avoid the need to pair each transport separately. Instead the user would just have to pair one of the two, which would automatically also pair the other one.

iOS 8.2 added support for (parts of) Bluetooth 4.2.
