My gut feeling is that putting more distance between the expression and
the package it was run in is not a win for me.  Plus you'd have to put
point on it to determine it that way which is quite inconvenient.

In a normal Lisp buffer I agree - its primary purpose is editing the
file, and interaction with the Lisp is secondary.  Having a
buffer-package shown on the mode-line works well in that case.  However,
I think the REPL buffer is a different story - interaction is primary
there, so I think the prompt works well (for me).

IMHO, no.  I like having the input indented by the prompt because it
helps delimit what exactly is input without relying on font faces.

Please experiment, though.  Just make the end product be a customize
option and everyone will be happy.  :-)
