I don't think that the error is really about the missing devices.
Most likely the real problem is that you are going too far back in history where
the data required to import the pool is not present.  It's just that there is no
special error code to report that condition distinctly, so it gets interpreted
as a missing device condition.
-F/-X/-T is not guaranteed to work as the old (freed, overwritten) data is not
kept indefinitely.
