I need to be able to give out raw multitracks, and expect to receive raw multitracks. Extra steps such as removing all plugins and so forth just isn't tolerable.
Here's what I got from the Steinberg forums: While there aren't dedicated checkboxes in the Export panel, as one might expect, there are multi-function buttons on the MixConsole that can bypass certain processes. Hold the Alt key and press "I," "E," "CS," or "S" to disable Inserts, EQs, Channel Strips, and Sends, respectively. These functions are also available via key commands so, for example, you could create a batch command that disables all of them with a keystroke and another to re-enable them.
Other options are available but sorta messy. For example, you can render files in place
(with the desired wet/dry options), but this drops the resulting audio files into your project's general audio pool and would need to be dug out manually. Hrmmmph.
