The compliancy is fairly irrelevant. Have a look at
this document. As you can see there are many states that comply completely with the provisions of annex 1, such as: Burundi; Fiji; Rwanda and Zimbabwe, to name but a few.
Then there are a large number of states that have notified the ICAO of their partial non-compliance with Annex 1, such as: Australia; China; India; The UK; The USA; Canada; Russia; South Africa; Germany; and France, to name but a few.
It hardly matters because to quote the relevant extract again:
States issue their own licences based on national regulations in conformity with Annex 1 specifications and validate licences issued by other Contracting States on the basis of bilateral or multilateral agreements or the fulfilment of nationally legislated requirements.
If there is a part of that annex those states do not wish to conform to, then they notify of a variance or non-compliance if (as table 3 shows) they can be bothered to do so.
