$wgSharedTables is pre-populated specifically with user related stuff 
for backwards compatibility since originally enabling $wgSharedDB shared 
only the user table, it had no option to share anything else at all till 
I added it.
The defaults for $wgSharedTables should only ever contain stuff to share 
users, but sharing users is not necessary. So if you've got something 
that uses a shared table (which would need configuration anyways) and 
people want to turn it on I'd say it would be reasonable to make setting 
$wgSharedDB and resetting $wgSharedTables to an empty array without the 
user related tables to be reasonable.
