Hello,
You reverted the Liège Guillemins station the "covered=yes" tag on the station platforms that I had removed because when this tag is present, the platforms are no longer visible on the map.
I find it unfortunate that in doing so, you do not take into account people who simply consult the map and who are therefore unable to orient themselves and find these platforms in the station.
I also point out that I couldn't find any stations where this tag is used, although the platforms are covered(Leuven, Namur, Charleroi, Gent, Brugge, Oostend, Antwerpen, Brussels Midi, Amsterdam Central, Lille Flandres, Paris Lyon , Köln Hbf, Hamburg Hbf, London Waterloo, London Euston...).
