[question] About data sources to be merged or discontinued

[mktktmr]

To developers,

Thank you for your daily maintenance efforts.

Currently, we are considering using zengin-rb that you are developing.
Therefore we would like to inquire about its data source.
In the event of bank or branch mergers, will the data for the merged banks or branches no longer be returned?
Or will data be returned indicating that they have been discontinued while still being retained?

Best regards,
@mktktmr
