I agree very much:

Level 4 & 5 : In reallity they are equal., but in OSM I prefer a 
separate level as it is now the case.
Both (region and community) deserve administrative boundary, as they 
have their parliaments.

If language regions are to be mapped, then certainly with another tag 
then administrative boundary (maybe language or etnic boundary???). 
Problem: How to map bilingual or facilities?
But I don't think this is needed or desirable to map in OSM.

Level 7 are the administrative arrondissements, the other could be 
mapped with judical and political boundary.
But as said earlier, I would maybe take the administrative 
arrondissements out and move to another kind of boundary as rendering 
this will not very useful and cluthering the map.

Level 9 is very useful, as some streets cross several sub-muncipalities, 
it is very helpful as you know eg Leuvensebaan Sint-Agatha-Rode or 
Leuvensebaan Ottenburg:
