I see this as a bug fix.
The current state of declarative partitions is such that you need way
too much foresight in order to use them. Missed adding a partition?
Writes fail and can't be made to succeed. This is not a failure mode
we should be forcing on people, especially as it's a massive
regression from the extant inheritance-based partitioning.
