At some lobbies, there's some parkour, try them :), Why not make your thread more specific? by telling why do you want it back and stuff.
But, parkour would be a neat idea, Maybe change some ideas? so it becomes more harder to people and this will make it more interesting + popular. Any suggestions about parkour, Please reply.

Here are some little parkour ideas ->
TNT Run parkour - Here, whenever you stand on the block and then jump to the other block, the block behind you falls, so you couldn't go back, this will make you go faster, It'll be more challenging.
Cactus Parkour - Where you take damage while doing the parkour, This would make it harder for you.
Ice Parkour - This will make you slide while jumping to other blocks, This could be very challenging.
Soul sand Parkour - This would slow you down, Which will decrease your jumps.
Head parkour - As head are so small, It could be hard to land on them.
These are just some ideas that I was thinking of (Don't Judge xD)

Thank you.
