I absolutely take your point but remember the reports include details of the following for every individual account you have in both participant countries of the DTA, including credit card accounts.

What information will be reported to tax authorities?
The information reported to tax authorities will have been provided in the self-certification form, and details about the accounts and products you have, including:
the balance or value
the total amounts of interest or payments credited
