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).

Beginne damit, das Modul aioble.security zu finden und zu überprüfen, wie derzeit auf seine Pairing-Konstanten verwiesen wird. Ermittle die Erwartungen an die öffentliche Benennung und Kompatibilität dieser Werte. Verifiziere anschließend, dass Anwendungen die bereitgestellten Konstanten importieren können, ohne sie neu zu definieren, und dass die relevanten Prüfungen erfolgreich sind.
