Giles looks a lot more advanced than what I was thinking about. I was really only asking about uploading texture data between the application and Horde (which is already supported), but for depth-textures.
Does that really have an application, beyond light/shadow-mapping?

Yes depth textures have applications beyond shadow-mapping... but I don't think that's what you're trying to get at, is it?
What objections do you have against allowing non-RGBA data to be uploaded?

If I used a 3rd-party tool to precompute some shadow-maps for a scene like you suggested, wouldn't I still need Horde to support a depth-texture upload?

Upload, no problem, but don't you need download as well for your idea? Texture download is a sticky problem altogether, even with FBO/PBO, and adding it to the API is going to encourage people (particularly beginners) to use it.

Yeah texture downloads shouldn't often be used inside the main game-loop, but I would love to be able to use Horde in my tool-chain as well as in my real-time-renderer.

I haven't used the Horde function getPipelineRenderTargetData, but it might already give my tools the ability to download the data I want from Horde...
