How often do you expect your mail server to lose power or crash? It isn't the end of the world if a busy mail server loses a few messages per year due to crashes. By extension of your argument, you could say that cars kill people, and therefore it's best to live far from cities and walk everywhere. Granted, I'm sure you could come up with a situation where a more conservative approach than softupdates is appropriate, but people who manage such important data probably don't use the default install.
