Yes, and that might explain why so are the fringes.

I don't know anymore who misses what.  You said:

which to me means that you want fringes to NOT be included in the
window text area.  Therefore, I tried to explain what was (or could
be) the motivation to INCLUDE fringes in the text area: because
otherwise, the display margins, which ARE part of text area, would
become disjoint from the rest of the window's text area by the fringes
that are in-between.
