Implementing anything like this will immediately lead to a stream of complaints that it doesn't support "all the weird and wonderful matplotlib features". The vector backends are actually doing something like this, but saving in their respective graphics languages instead of in python. Presumably some sort of "matplotlib_script" backend could be written, using the pdf or svg backend as a template. Better practice is to use something like the ipython logging facility to save one's interactive commands, and then manually to edit that down to a script that creates the desired figure. That way one retains full control, reproducibility, and documentation of what went into a figure.
