Disagreed. Given an arbitrary byte string, you can't know whether it's
semantically text or semantically an array of bytes. (Sometimes a good
byte array is just a byte array?)
In the past, I've done plenty of work with "strings" (in the generic
sense) of octets to/from wire-level protocols. It would have been much
easier had Python *not* tried to pretend they were text, and *not*
rendered some of the bytes as their ASCII equivalent and some of the
bytes as hex escapes (especially in the cases that some of the bytes
happened to be 0x58, 0x78, 0x5c, or in range(0x30, 0x3a)).

Curmudgeonly C programmer that I am, b'p' *is* 112. ;-)
Quick: how long is the byte array that displays as '\xff'? Too easy?
What about '\0xff' and '0\xff'?
FWIW, Erlang, a language all but designed to read/write wire level
protocols, prints any array of integers less than 256 as a(n ASCII) text
string. It never *mixes* integers and characters, but often picks the
