Hi Juri:

Up to now we are only dealing with the first two cases... The third one
will add even more complexity (and corner cases when dealing with dfci)
for a very low gain (in my opinion) because I don't find yet any use
case for it. I am not telling it is impossible, just unneeded.

If you have a good use case for it, please share it.
