Why are these pairing parameters in aioble.security module private?

The aioble security module defines several very important constants needed for pairing such as

_IRQ_ENCRYPTION_UPDATE = const(28)
_IRQ_GET_SECRET = const(29)
_IRQ_SET_SECRET = const(30)
_IRQ_PASSKEY_ACTION = const(31)

_IO_CAPABILITY_DISPLAY_ONLY = const(0)
_IO_CAPABILITY_DISPLAY_YESNO = const(1)
_IO_CAPABILITY_KEYBOARD_ONLY = const(2)
_IO_CAPABILITY_NO_INPUT_OUTPUT = const(3)
_IO_CAPABILITY_KEYBOARD_DISPLAY = const(4)

_PASSKEY_ACTION_INPUT = const(2)
_PASSKEY_ACTION_DISP = const(3)
_PASSKEY_ACTION_NUMCMP = const(4)

I don't understand why they are private. These same constants are needed in any pairing request invoked by the application which means the application must redefine them. I think I can still use them though linters will complain and that would violate policy. Can't they be made public or did I miss something (my search did not find any public set of such constants).

Start by locating the aioble.security module and reviewing how its pairing constants are currently referenced. Determine the public naming and compatibility expectations for these values, then verify that applications can import the exposed constants without redefining them and that relevant checks pass.
