   You again assume that DOS and Windows behave like Posix systems; they

   size.  With such a version of `stat', autorevert will work like it
   does on Posix platforms.

Not completely.  When renaming a file to a name with the same length
(common when one made a typo, when updating a version number, changing
a suffix and so on), dired would not get notified.  So even with your
suggested version of stat, looking at the directory size would seem to
be clearly inferior to the prior suggestion of listening to the
messages delivered when a directory changes.

Anyway, the question is whether one can find anybody willing and able
to implement either of these suggestions.  I would say, preferably the
"listening to the messages" one.
