I didn't actually realize one could fit so much into such a small barcode. I do wonder if this now means it is in theory possible to track items sent by letter

  It is. Other european mail services, e.g. DHL, have been offering tracking for every new stamp for a while now.

  We forget just how automated sorting of mail now is. Only probable manual part is by the person doing delivery, and that is just for their own convenience. Everything else is automated, with few hard to read addresses going through manual sorting. Where they are tracked too.
