Now mp code is processed by luatex through the mplib without to call
the external system program.

I think so, especially when dealing with non-metapost data ( for
example, use lua to parse/process the data and push them to the
mplib).
Lua is more like a programming language than metapost, new users will
learn it with less pain, of course.
I strongly suggest there should be such a interface.
but Taco said such lua interface might never exist:(

Last year, Hans made a new math interface like TI calculator based on
Lua to show it is powerful.
I think such Lua like metapost interface can also exist even it is
somewhat incomplete(neglect the linear equation solver, for instance).

Of course. try the minimals.
