That is fantastic, I was going to put that on my todo list.

I saw the bug report with the patch (78594)

I guess am hoping that we will reach the consensus that "Sprinkling
ISerializable on [Serializable] classes that we cant make compatible is

These lookups are also fairly expensive.

In fact the runtime actually "fakes" [Serializable] (well, they call
them synthesized attributes, or something like that), and the
"Serializable" bit is actually turned into a bit in the method
definition for fast lookup.
