Everyone has personal preferences, including you, @Yog Sot. You've already aired your personal insults on the forum. If I may ask, please refrain from doing so in the changeset comments.

In the Tricity area, pedestrian and bicycle paths without physical separation are drawn with a single line, and this is the local community's decision. It's also visible on the map that this is the local standard.

Drawing such paths with two lines remains controversial (https://wiki.openstreetmap.org/wiki/Pl:Rowery#Różne - ref S5), and forum posts suggest that nothing has changed.
