I think there is no point in actually describing any object model at this
point. It's just too early. That will have MUCH debate when the time
comes.

again, an implementation detail.

If a plugin is smart, it can see that a buffer is 'silent' without actually
needing the data. This saves the cost of filling the buffer, and possibly
more, if the plugin can optimize away certain paths.
In XAP, we called it the SILENT flag. Some people hate it.
