Perhaps this is a meta meta question, but I wonder whether experience and reputation on other SE sites should not be taken into consideration when granting certain privileges, such as those to review close votes, for example.

Consider, for the sake of argument, a relatively new member of Academia SE who is a long serving academic and also a high-rep member of another SE site, where they possess, say, review privileges and know the general gist of SE very well.

One way to implement this would be to use a formula based on a combination of SE sites, say Academia SE rep + 10% of rep elsewhere on SE.
