Would it be ok, if I added levels 6 and 8 to Wien as well? I have found a wiki page about your boundaries [2], but I dont understand if its on purpose.

No, the usual way is to give an area the highest admin_level (lowest nuber) of all possibilities.

Eg: Berlin in Germany. It's city (al8), county (al6) and state (al4). so it has only AL4.

btw: Austria just removed those redundant AL of vienna last year.
