If I may jump right into the discussion and perhaps miss the point:

Some of my latest docs involving pretty narrow \hsize would have been undoable
without hz (tons of overfull boxes otherwise). While I've tired my eyes on page
191 of Bringhurst's /Elements/ to no great avail (barring the line-by-line
comparison, of course), it seems to me that hz can be spotted when comparing
narrow paragraphs with and without it (something in the text's color, although I
might be cheating myself here); anyway, hz (meaning character expansion only
here) is one of the (many) reasons why I moved from XeTeX to LuaTeX, and with
regard to what I can do now, I couldn't live without (to the extent that I
haven't tried not to use it with comfortable \hsize... I should do the test).

Pages on the same leaf wouldn't align though. It depends on the paper, but
sometimes it's annoying (and sometimes for me it's just "ha ha, no grid! damn, I
ain't disturbed... I MUST find a way to be disturbed, I can't allow no grid!",
and then I feel quite pedantic and almost a fraud).
