Yes, I was looking forward to read the section on IBANs, before it never came. Then I noticed the article being from 2000. IBANs weren't in use at that time.

At least in Germany IBANs are not very popular. Compared to the national numbers usability has decreased a lot.

Previosly the was bank id in a nice 3-3-2 grouping. Because there are not so many banks the numbers were systtematically and sparsely assigned. When I was a student in Germany I had 600 100 70, I remember it decades later. Account numbers were variable length, most banks did not have very long ones.

With IBANs the bank id remained unchanged, but the grouping got very weird, so it's hard to recognize and remeber. Account number have been padded with leading zeros to achieve a fixed length IBAN. So the nice short numbers ended up with long runs of zeros, not at all user-friendly. In the old days I knew several accounts by heart. For IBANs I do not naturally remember a single one (I know how to construct the from old numbers, but it's a tedious process not happening in a couple of seconds.) Typing a German IBAN is a nightmare every time.
