Make a respawn location be less accurate every death - If you sleep in a bed and then die you will respawn next to it, if you die again without using the bed you will respawn maybe (random) 0-100 blocks from spawnpoint. Next death will cause you to respawn even further from your spawnpoint (50-500 blocks).

The bond with the spawnpoint will become weaker every time you die without making it stronger by sleeping.

This is a more advanced version of #68. I think both should be implemented but #73 seems more fun.
