Why not have a recvall method?

[陶青云]

makefile('rb') return a  io.BufferedReader and the doc(https://docs.python.org/3/library/io.html#io.BufferedIOBase.read) says:
    If the argument is positive, and the underlying raw stream is not interactive, multiple raw reads may be issued to satisfy the byte count (unless EOF is reached first).

I am not an expert on sockets, but since f.read(n) will read a maximum of 
n bytes, isn't that the same as socket_obj.recv(n)?
