The present ABC was the Archbishop of Wales prior to taking up office. The next ABC will be chosen by the current Archbishop of Wales, with help from a committee :)
We all know instances where appointing committees, disappointed with the quality of applicants in front of them, turn to one of their members and ask whether they could do the job ...
Still, it is only the ABC they are trying to sort out with Welsh help. Imagine if they were choosing a rugby team to beat the All Blacks.*
For those with impoverished lives, the last time Wales beat the All Blacks was in 1953.
