"may" have an effect is a serious understatement, surely? Especially
in languages with long compound words, like German and Finnish,
hyphenation choices will drastically affect how many lines some text

So maybe I should restate my claim then, and say that an ODF document
can specify things like column widths and inter-line distance quite
precisely, but in general the number of lines and thus vertical space
taken up by a paragraph of text is up to the rendering client.

This is not a critique of ODF, far from it. One should just not
misunderstand what is possible.
