Create .logarchive files programmatically?

Is there an API to create a .logarchive file from the contents of e.g. a OSLogStore?

There is not.

If you’d like to see such support added in the future, I encourage you to file an enhancement request describing your requirements. Please post your bug number, just for the record.
