Comment (by nacin):

 We can start with this for now to suppress the E_WARNING on these
 installs.

 Unfortunately, changing a table prefix requires a bit of work -- all
 tables need to be renamed, and a number of user meta keys will need to be
 updated. Not having a prefix to go on makes it really difficult to figure
 out which user keys need something prepended. It's a mess. So I don't feel
 too comfortable simply adding a note to network.php without coming up with
 some way to resolve it or document what to do.
