Well, tbh, I don't know the reason, I can only speculate. It is meant to encode pure binary data (cbor) and not to be human readable or URI or anything like that. It is specifically designed for QR Codes. I read through some Github issue [1] just now and as far as I can tell, it is more or less a design oversight, which might be remedied by a later version.

In I faked tons of Covid passes – “Weak Key Cryptography in real world”
denysvitali·Oct 30, 2021
The private keys didn't leak (at least publicly). What happened is that North Macedonia (among other countries [1]) was running a public facing and without authentication (or w/ hard coded credentials) server used as a frontend to generate the COVID-19 certificates for their country. You can follow the discussion here [2] and read my comment [3] here. On top of that, you can follow my analysis on this repo (RESULTS.md contains the generated results) [4].
