I get it. You want a pony, and you don't want to pay anything for
Any language is fundamentally broken if it has no concept and/or
method for ensuring data integrity for data that is written through
it. If you have such a language and you need data integrity then
your only filesystem option for guaranteeing no data loss is
synchronous writes and metadata updates.
XFS allows you to minimise the impact of such legacy languages and
applications to just the data sets those applications use through
the use of 'chattr -S' and the /proc/sys/fs/xfs/xfs_inherit_sync
