I think you're right, BUT...given the horribly inept way that this government has handled things so far, it's not a great surprise that any of the imperfections inherent in the system (suddenly having to change international traffic flows due to the appearance of a new variant, for example
) will tend to look like just another example of their incompetence, even if on this occasion, it's not entirely, or even slightly, down to that incompetence.
FWIW, even though there is not much different that they could have done at this point, I am very pessimistic that they will break with tradition and suddenly handle this new challenge effectively, or well.
