Basically, yes. First, careful write requires a huge amount of
discipline in programming. Second, it imposes some restrictions
that are inconvenient - no double-linked structures. Third,
sequential writes to a log file are faster than scattered writes
directly to the database file. And, as you point out, intermediate
layers make reliable writes harder and harder to guarantee.
