Description

First, sorry for skirting the default fields, I'm opening this here for discussion and exposure.

Times have changed, classic Bluetooth has become, well, classic, yet the default Bluetooth/BLE stack is still Bluedroid, even though no other Espressif SOC except the original ESP32 has supported Bluetooth classic, why?

This is detrimental to the users that are using one of the many other MCU's that are not the original ESP32.

The latest release has shined the spotlight on the issue, as of now the NimBLE-Arduino library is not able to support the C6 and H2 variants in the 3.x.x releases because the libbt has Bluedroid enabled and the controller is NimBLE based which causes all kinds of conflicts. Would it not make sense to enable NimBLE host for the "other-than-original-esp32-devices" and incorporate the supporting library esp-nimble-cpp, which NimBLE-Arduino is derived from and many use?

Alternatively, maybe have an option to select the BLE stack and link a different 'libbt' for each stack?

If none of this is viable, I understand, close this at your leisure, just thought I'd open some discussion.
