There has been a short update on this issue on the dutch AOPA site. Follow the link in the first post to see the update. (Text in dutch)
I think the gist of the text is this:
The dutch minister has in answer to questions in dutch parliament told that she will look into the inconsistencies in the current laws and if necessary change them so the current use of airspace by general aviation in the Netherlands can be upheld.
I think this can be seen as a glimmer of hope?
