i thought a reason, but with some my assumptions, i'm not sure if
is valid for you:
1- never change existing variable names expecially if related to
  customizable names unless really necessary
2- choose the name which maximixe the meaning when introducing new
  variable names.

i suppose the cronological history of this faces is:
+ modeline (aliased)
+ mode-line
+ mode-line-inactive
+ fringe

when i was partitioning the fringe face concept into active and inactive
meaning i was in dubt becouse  i suppose (1) i can't change existing names,

and in my mind "inactive" without express "active" is unexpected logic,
because "inactive" is etymologically a word which extents "active".
i didn't choose fringe-inactive by this opinion.

But now, in more conservative point of view i can find a reason to
imitate mode-line-inactive logic:
when existing(/previous) unique fringe face is whatched by the user,
the name is "fringe" and it is implicitly thoughts "active"
in current window, even if there was not distinction.

Anyway I temporary (locally) change the name in
 to fringe-active and fringe-inactive, and
put an alias fringe (put 'fringe 'face-alias 'fringe-active),
you can expect a new patch relative to the original emacs,
after i sign copyright disclaimer papers,

Anyway i have to say: in previous patch in xdisp.c there was wrong asignment
to Qfringe, the second assignment should be to Qfringe_active in previous
naming logic, and this explain the surprise noticed and commented
in the same file:
xfaces.c in line 7705
-  Qfringe = intern ("fringe-inactive");
+  Qfringe_active = intern ("fringe-active");
relative to that patch

actually i have connection timeout to port 22 of savannah.gnu.org
