It is clear that this is a controversial issue. Perhaps the resolution
is to add the option, but require a compile time configuration to
include the feature. Then it would certainly have zero impact on anybody
who chose not to include it in the binary. If you have it in the binary
but do not turn it on, the impact is a flag test every time Exim might
do an fsync(). I suspect this is a very small cost compared with
everything else that's going on.
