These are often confusing for new contributors, since this looks suspiciously like the right place to add new functions or change the behavior of existing ones. To reduce that confusion, here we remove them entirely from this package (which is now dead code in Terraform 0.12 anyway) and include in the documentation comments a pointer to the current function implementations.
