I think most graphics hardware is able to read/write directly to system memory
and with large textures and offscreen windows using a lot of memory it would
be inconvenient to not be able to store them in system memory without losing
hardware rendering.

The security part I don't really understand. Do you mean to not provide
any way for the graphics hardware to write to system memory? I don't
see how reading from system memory can be avoided...

It may be a simplication, but it is also, IMHO, a serious drawback.

One might even want to have local memory act as a cache for system
memory, but you'd need the graphics hardware to be able to read/write
to system memory to be able to do so also..
