To be honest, I very rarely even use pprint. I'm too lazy to import it. If I want to quickly get a hexdump, I use something like `' '.join('%02X'%i for i in data)`. It is shorter than `import pprint; pprint.hexdump(data)`. For a small program most likely the standard hexdump() will not be enough.

Agree. Of course it would be better to automatically determine a "nice" display (use hexdump only for large non-printable bytes).

If you want to print bytes in hex, why not ints and floats? ;)  In fact I don't want to print data as hex, so shut up.

Perhaps I misunderstood your wish. I'm not against consider pprint as a black box, which does all good magic inside by default. The use of this feature does not require anything from the users and does not impose obligations on the maintainers. But I'm not interested in a separate function.
