I have updated the draft, with a more specific description of how the
process of final page float placement takes place [1]. For now I have
simply specified that floats in the block direction by default fill the
entire size of the line size and the other way round. This basically means
that there cannot be floats that go up/down AND others that go right/left
within the same float reference.

This simplifies the situation, but it also means that some effects cannot
be achieved. Also, we may want two-dimensional floats, right?

The mentioned process description [1] should make it clear that there is a
distinction between the two, and only the manual change fo float reference
through float-defer is called "float deferrence".

If you wanted to achieve that effect, couldn't you achieve the same effect
by adding a left margin to the float?
