To clarify my previous message: I think we will remain mostly at the mercy of numpy, which may change from version to version, to determine what we can handle. Apart from registered unit types, we fall back on numpy, typically masked_invalid, to handle inputs. If we really want to handle Decimal reliably, then it probably has to be done within the units framework.
