says, for \ooo, "In a bytes literal, hexadecimal and octal escapes denote the byte with the given value. In a string literal, these escapes denote a Unicode character with the given value."

I agree that sometimes truncating an invalid integer instead of always raising ValueError is strange.

>>> ord(b'\407')
7
>>> bytes((0o407,))
...
ValueError: bytes must be in range(0, 256)

I don't know is there was an intentional back-compatibility reason for this.

Without an example of re raising, I don't understand the re complaint.
