On Monday May 26th you stated:
"The point is that we are not fully sure what will happen in July/August this year. According to my colleagues, we created the scenery knowing that it would be L/R, so we somehow made this new scenery in a future layout. We did this small update for the time being, but we don't want to spend more time on something that might change in just 2 or 3 months."

It looks like you and your colleagues were correct in your assumption.
