Only what has been transferred off site can be considered safe.
But: all the WAL improvements serve to reduce the probability that
you 1. need to restore and 2. need to restore from offsite backups.
If you need to restore from offsite backup you loose transactions
unless you transfer the WAL synchronously with every commit.
