It would be very useful for automatically populated ender chests/ender pouches, if we could craft an ender chest variant that emitted a redstone signal when it was open.

Didn't see this, so pardon my late response. I don't really see an issue with this. However, I expect it to be awkward, as both locations need to be loaded for the signal to propagate. Then again, many people have their areas chunk loaded, so that might not be a huge deal.

I'm on board with this, fairly simple request. @Ecu thoughts?
