update: "deprecate" call to 'merge.update' without a destination
Now that all internal callers pre-compute and set a destination at a higher level
it feels like we can kill this API. This will allow us to simplify this
function. However I feel like this is a bit too central and critical to break
now. I'm adding a devel warning to let extension make catch this in the next
cycle.
