These packages are frozen copies of old code from much older versions of
the product that are preserved to keep the state storage backends working
until we decide on a way to get them out of this codebase entirely.
Therefore the only potential future change to this code is to delete it
once it's no longer needed. It would not be worth the risk or time
investment to rework these to meet our strict complexity linting rules.
