Hi again
I dont think notes such as these are a burden. 
To quote the wiki: 
"[...]indicate where there are errors or omissions in the OpenStreetMap data [...]" 
Even when a note doesn't contain every bit of information needed to solve it, it still helps in the long run. Either it gets the issue to attention or it just takes a while until a survey using streetcomplete for example can provide more info.

Not every note needs to be solved within days, at least thats how its handled in my area

And i was wondering, is this account used by multiple people - or does "we" just refer to brussels mappers?

Thanks for the survey and updating the map :)

Cheers
