I plan to make support for Daschan in the future, at least while this solution will work for 2ch, if possible. It may be worth implementing a separate module for this, because will need to implement a completely new API in the client.
I also don't see blockers for posting similar images on other sites, so users can use steganography everywhere.
Some users use steganography as an example solution for 2ch.hk: https://github.com/anon25519/hiddenthread

This is a long term feature for now.
