Make rails visible on maps

Why is track invisible to maps?

On my own server since 2020, I have made roads (and then rail) to 17 villages and a handful of rail stations. I get that there is no way to mark a road on a map. However, I think it would be very handy if maps could draw the rail placed in the overworld as a thick black line or a small track seen on like google maps today. 

What I am having to do is cut all trees out of the way and place opposite color blocks to lay track on to these locations to get them visible on a map. It is a lot of work. 

I understand not showing track below ground and those I tunneled should not be seen. However once the map is made it should draw track layed by a player visible from the sky like any other block. 

I can't believe I didn't see this suggestion. 

Thanks in advance
