Not strictly necessary. We could use a variable-length encoding for txn 
ids longer than 32 bits and mark such records with a new flag. It would 
add zero storage/performance overhead for all the current applications 
but allow longer txn ids for the slightly bigger cost. It would increase 
the code complexity though.
