I imagine it organized in such a way that it can communicate with a
program able in the first place to talk natively with std in/out/err,
separating input, output, exit/result code and the prompt.  By means
of escape sequences and a filter, a given shell can talk to that other
layer of the protocol. The insertion of escape sequences stays
possible with filters for any given shell.
