Thanks for the insight Terry.
I think the functions that accept ints as bools are kind of a red herring:
Booleans were only formally introduced in Python 2.3 [1], thus any functions
that existed before that accepted ints and continued to accept ints for
backwards compatibility [2]. When transition to argument clinic, these
functions use "bool(accept={int})" which restricts the inputs to either bools
or ints [3].
print, int.to_bytes and int.from_bytes all use argument clinic's bool converter
which accepts any truth-y objects. This is similar to PyArg_ParseTuple's 'p'
parameter which also accepts any truthy objects as well as say the print
function which manually does a PyObject_IsTrue [4].

[2] list.sort (sorted) existed since the start of Python:
https://github.com/python/cpython/blob/85a5fbbdfea617f6cc8fae82c9e8c2b5c424436d/Objects/listobject.c#L423
splitlines exists in Python 2.0:
