Ok, there might be a bug. No surprise. :-)
This needs to be analyzed and covered with tests and possibly
fixed. No reason to veto, imho.

Well, it was not a lot of time...
There will be more tests soon.

No, this is not about promising!
I don't think anyone has promised anything to Kai.
It is rather about people supporting the default change
now that the code is basically complete.
It is also not a conspiracy, it is simply that people
seem to like the step.

Well, we seem to have reached an impasse in that.
I don't see that using the incomplete tests as a lever for
blocking the default change is valid in this particular case.

But unfortunately, I need to drop off this discussion for tonight
to get some sleep...
