That's a feature. Killing the app outright would prevent useful things, like being able to create a prefix without a display.
That makes sense for wineboot (I use that feature quite a bit), but for something like winemine, which has no cli mode (even /?) it doesn't make as much sense.
Of course, separating the two cases may be difficult and not worth the trouble.
