Hope your approach won't require too many changes. I think appending mode will be more common among FOSes which will be attempted configured with policies. For example, log files are usually held indefinetely open in append mode. While randomly accessed files are likely to be related to some work in progress state, and may require more complex handling. So limiting implementation of policies for appending FOSes will be simple yet useful.
