You don't need to go so far. Even the Unicode characters can be
entered: A0 0A (which makes for a nice smiley like pattern, two ears
besides two eyes 😉).

Obviously we are talking about *automatic* linebreaks. IIUC the point
about NBSP is that *it itself* doesn't break, whereas SP breaks up and
is *replaced* by a linebreak.

Nobody said anything about manual linebreak characters *following* a
space character, whether SP or NBSP or anything else.

I also just tested and noticed something related: in my wordprocessor
(LibreOffice Writer) when the cursor is near the end of a line and the
horizontal space remaining on that line is less than the nominal
advance width of the space, pressing space doesn't advance the cursor
(or maybe it does and I don't see it) irrespective of whether the
paragraph is left-aligned or justified, whereas inputting NBSP goes to
the next line, pulling the word before it along with it. This is
consistent with the current fixed-width NBSP behaviour of these
wordprocessors.
