Agreed.

That is indeed the question. I rather suspect the formatting gains
would be minimal. That said, if, as I posted earlier, paragraph
insertions begin by switching environments, then collecting the
entirety of a logical paragraph makes sense, leaving us with the
original premise that whenever a break is introduced into the text,
it signals the end of a chunk of text to be adjusted.
Ted--how often do you come across a situation where a paragraph
insertion has fully justified text above it, ie the last line is
justified? IOW, this
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed at
ante. Mauris eleifend, quam a vulputate dictum, massa quam
dapibus leo, eget vulputate orci purus ut lorem. In fringilla mi <=
sentence continues
paragraph insertion
in ligula. Pellentesque aliquam quam vel dolor. Nunc adipisc‐
ing. Sed quam odio, tempus ac, aliquam molestie, varius ac, tel‐
lus. Vestibulum ut nulla aliquam risus rutrum interdum.
rather than this
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed at
ante. Mauris eleifend, quam a vulputate dictum, massa quam
dapibus leo, eget vulputate orci purus ut lorem. <= break
paragraph insertion
In fringilla mi in ligula. Pellentesque aliquam quam vel dolor.
Nunc adipiscing. Sed quam odio, tempus ac, aliquam molestie,
varius ac, tellus. Vestibulum ut nulla aliquam risus rutrum in‐
terdum.
