See my posts below, would take far too long to link vaccination records through passport databases to make this realistic for 2021-2022 resumption of travel. Although I agree with you, we are decades away from the global consensus needed to achieve what you correctly say is technically possible today - something called politics and NOT wanting to be accountable for the mistakes made in other countries generally reigns in this kind of inter-state policy decision-making.

You are looking at this from the end of the generally legitimate travelers, whereas border control policies start with the premise that even the smallest error in interdiction efforts can cause major calamity - which is a clear lesson from the 9/11 Commission that errors were made in processing just a handful of people at both Embassies abroad and then upon arrival at U.S. Ports-of-Entry.
Rather, as I explained below, would only take few forgeries to create havoc amongst border control agencies everywhere. Forgery of the U.N. WHO compliant Yellow Book already exists, and as countries are all making up their own C-19 vaccination records, how will a border control agency in another country know what is real and what is not.
Unfortunately, in the world of border controls that I know well, only takes a VERY FEW bad apples to make cross-border travel difficult for everyone else.
