Given the sheer number of people who use (or have to use) Word, this
is hardly beside the point.

I disagree.  I've seen that happening during pretest many times.
Heck, even the discussion we are having now is part of that feedback.
And I don't expect it to be the last discussion about this.

For now, the release is still so far away that any difference between
these 2 alternatives is indiscernible, IMO.

Yes, but we don't change the defaults on behalf of such a small
minority, except to prevent a disaster.  I see no disaster in this
case.

Not "for Scandinavians", in text written in one of the Scandinavian
languages.  Right?

Then these users will customize their Emacs, and move on.

Indeed.  But I don't see that as a sufficient reason to decide now
that the default should off for _everyone_.

I read everything that is posted to this list.

Emacs ceased being American-centered long ago, around v20.1, I'd say,
if not earlier.

If you really think that, I'd encourage bug reports about any feature
or misfeature where this attitude is visible in practice.

There was at least one opposite view expressed in this discussion.
Which just tells us that one size will not fit all in the is regard,
there's nothing new.  But it tells nothing about which default is more
correct.  The default you propose has disadvantages, not just
advantages.
