I noticed some during review, but not many. As far as I know, they are still not eligible.
Very recently I tried re-instating one of them, to see if Niantic’s stand on these is still the same, and it was. See thread: Wayspot restoration request: Dutch trail markers - #10 by MachokeOnDeez
Those signs are still considered directional signs to ‘hubs’ (knooppunten), and only those larger hubs are eligible. The rest of the signs are removed en masse by Niantic.
There are few who agree with Niantic on this topic though, including me. But hey, it’s their game.
