I understand that. But it's not relevant - cvs-fast-import doesn't know about
git SHA1s, and cannot.

You give it a cutoff date. This is the same way cvsps-2.x and 3.x worked,
and it's what the cvsimport wrapper expects to pass down.

As I tried to explain previously in my response to John Herland, it's
incremental output only. There is *no* CVS exporter known to me, or
him, that supports incremental work. That would be at best be impractically
difficult; given CVS's limitations it may be actually impossible. I wouldn't
bet against impossible.

Sorry, I don't understand that.
