You're not mistaken. We had a provision for side-by-side boxes
earlier. (We referred to it as the `upside-down Tetris model' since it
caused blocks of text to move up into space left empty by other
However, these boxes couldn't do run-in headers, only side-heads. And
even for those, the difference between putting the heading in a float
and putting it in a side-box appeared not enough to warrant this extra
feature. Some implementers also asked us to take it out. It also
didn't correspond to any easily visualized model (apart from Tetris),
and writing style sheets that used it was difficult.
Simulating columns with side-by-side boxes also only worked up to a
point, and the didn't really replace tables either. So we decided to
take it out and work on real run-ins, real columns and real tables

Yes, there was. But there were no percentages or 0-255 ranges then. We
decided that 0-255 was so common that it was certainly needed, and
that percentages expressed the limits of the range better than
0-1. Using percentages also removed a possible ambiguity: is
rgb(1,1,1) white or (almost) black?
(The doubling of the line about 0-255 is an editing error.)
