As far as I am aware, that last item poses the only open question, with the alternative being to add an "iterbytes" builtin (...)

Do you have examples of use cases for a builtin function? I only found 5 usages of bytes((byte,)) constructor in the standard library:

$ grep -E 'bytes(([^)]+, ))' $(find -name ".py") ./Lib/quopri.py: c = bytes((c,)) ./Lib/quopri.py: c = bytes((c,)) ./Lib/base64.py: b32tab = [bytes((i,)) for i in _b32alphabet] ./Lib/base64.py: _a85chars = [bytes((i,)) for i in range(33, 118)] ./Lib/base64.py: _b85chars = [bytes((i,)) for i in _b85alphabet]

bytes.iterbytes() can be used in 4 cases on 5. Adding a new builtin for a single line in the whole standard library doesn't look right.
