I think your understanding probably comes from listening
to the marketing folks, but, yes, that's the general idea. :-)

Uh, mostly to tide you over until 2018. :-)
Or, alternatively, to give you graphics commands that are
fast, simple to build, and work intuitively, none of which
applies to new graphics commands, although maybe you
could argue the last point. But when an image appears as a
tiny dot in your graphics window and surfaces have
axes that are obscured by the data, you wonder if anyone
is actually thinking about how these commands are suppose
to be used by people who are trying to get some work done.

It's not that anything has gone wrong with the new graphics
objects, it's just that not all that much has ever gone right.
I still have hope, but not enough to stop publication of
a book on traditional graphics, which I think people will
still be using 10 years from now, when we are on the 6th
(or will it be 7th) "new" edition of the New Graphics.
Sooner or later, we are going to have to get something
simple or we will never get enough bugs out of it to
make it useful. IDL 8 graphics are clearly a step in
the right direction. But I have my doubts about whether
they are the final answer.
In the meantime, there will still be software available
that gets the job done in a simple, elegant way. :-)
Cheers,
David
