AFAIK, no.  I found this problem because pages were being touched after
I scanned for pages to be migrated -- the result was that pages that
had not been touched by the application were being touched and then
left on the old nodes.

For the moment, I'm still pursuing a strategy of getting my manual
page migration code to work without the migration cache -- once I've
got that all working I'll come back and revisit the migration cache
bug I had reported.
