For the record, on ru.wp current arbcom there are three sysops and two members who are not sysops. We have never had a sysop-only arbcom so far.
And the non-sysop members never need e.g. to see deleted pages?
I have never been an arbcom member myself, but I assume if there is a case on restoring an article, another sysop (for instance, another arbcom member) can restore an article to the user space so that it becomes available. For sure, they do not have any sysop privileges: For instance, just today one of our non-sysop arbcom members placed a request to block a vandal at the sysop request page.
