Because *that* implies revealing infrastructure status details to 
end-users, which is probably not desirable in a lot of cases.

Isn't this as simple as not lying to the user about the *server* status 
when it cannot be ascertained for any reason? In that case, the user 
should be given (only) that information, but not any "dirty laundry" 
about what caused it....

Even if the admin doesn't care about revealing infrastructure status, 
the end-user shouldn't have to know that server_status can't be trusted, 
and that they have to check other fields to figure out if it's reliable 
or not at any given time.
