Revert "Add mapper-wait-until-removed"

This reverts commit 9f4c3c7c408a5f84a52416da99d0dd8035f1ae5a.

After further design discussions, the new wait until
removed implementation should be a new API. Reverting this
change to put back the original wait interfaces since new
ones will be created instead of modifying the existing ones.
