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).

首先定位 aioble.security 模块，并检查其 pairing 常量当前是如何被引用的。确定这些值在公开命名和兼容性方面的要求，然后验证应用程序可以导入已公开的常量而无需重新定义它们，并确认相关检查均已通过。
