No, cvs-fast-export does not have --export-marks. It doesn't generate the
SHA1s that would require. Even if it did, it's not clear how that would help.

Confirmed.  Looks like ibiblio is having a bad day.  I'll file a bug report.

That's the "stability" property that Martin Langhoff and I were discussing
earlier.

cvs-fast-export conversions are stable under incremental
lifting providing a commitid-generating version of CVS is in use
during each increment.  Portions of the history *before the first
lift* may lack commitids and will nevertheless remain stable through
the whole process.

All versions of CVS have generated commitids since 2004.
