So based on that, I suggest we go ahead and make the change to make both
the values 10 by default. And that we do that now, because that lets us get
it out through more testing on different platforms, so that we catch issues
earlier on if they do arise.

It would be interesting to find out why it's limited as well, of course,
but I don't think we need to wait for that.
