Yes, I understand the usefullness of this technique.
Well, probably by the next release; shouldn't be a lot of work to do
since essentially it is the same as floats.
The problem, however, is that fo:block-container may create multiple
areas. (That is, in XEP it can unless it's height is explicitely given).
If the space on the current page is enough for the image but not for the
absolute block-container, then the block-container may end up on the following
The only solution I see right now is to limit placement of absolute containers
to block-containers with explicitely defined block-progression-dimension.
Correct me if I'm wrong.

Well, z-index is a good thing. It is possible to do great things without
this feature. Unless we get paid for the implementation, it will wait
till we finish other things.
