If it is used for testing only, can it be named TokenSerializerForTest instead?
That way it is more clear that it is not for production use.

well; it can also be used by code that's not sandboxed... so that's why i didn't
put test in the name.

I feel that it is a little inaccurate to name testing/non-sandboxed code
"Default". Maybe we could consider NonSandboxedTokenSerializer to make it
obvious?
