Not every one-liner needs to be a builtin...
Until your post just now, there has probably never been anyone anywhere who wanted to display b'Abc' as "41:62:63", and there probably never will be again. For such a specialised use-case, it's perfectly justified to reject a request for such a colon-delimited hex function with "not every one-liner...".
So I picked a bad example. Sorry. Someone (sorry, I can't recall who) did ask for
print(' '.join("{:02x}".format(c) for c in b'Abc'))
41 62 63
My point is that a simple pattern is flexible, a specific method has to pick one "obvious" representation, and there have been a number of representations discussed here.
