We can't immediately switch to using sizeOfTagged since many people
will still be using old versions of base. If we waited one cycle to
deprecate the old functions, it won't annoy people. By the next cycle,
in theory a majority of people will already have sizeOfTagged, and it
would be feasible to switch our code to sizeOf.
