When I worked on this a bit more than a year ago, I was able to
record (some of) the menu entries belonging to the core, such as
Layers->Flatten Image, Image->Scale, Image->Mode->...  I do not
remember exactly how I did it and I think that it was not very
elegant, but it seemed to work.  I think that I had to modify each
core feature separately and add a hook using the GimpScriptRecorder
object before the end of each function.

The biggest problem for me was to generate the equivalent PDB calls
for brush strokes, gradients, fills, selections, etc.  Especially
since I wanted these to be scalable (see my comments in bug #51937
for details).

This is fine if you want to record a complete GIMP session from the
beginning to the end, but this is probably the least frequent usage of
a script recorder.  I expect that the most common reasons for using it
would be:
- to apply similar operations to different images,
- to repeat a sequence of operations several times on the same image,
- to get a skeleton of a script that you can edit later.
Gerd does not solve any of these problems, unfortunately.

Those who do not know what Gerd is can have a look at these links:
  http://bugzilla.gnome.org/show_bug.cgi?id=51937
  http://www.gtk.org/~timj/gerd/
By the way, the last time I checked (end of last year), Gerd was only
working with GTK+ 1.2, not 2.x.  I don't know if it has changed since
then.
