Devs,
I opened 
https://github.com/treeverse/lakeFS/issues/5611 to modify GC to write expired addresses only once.  I am trying to figure out whether there are any reasons 
other than historical for doing so.  I shall be 
removing the extra writes tomorrow.  So if you have any reason to care or insight about where to write expired addresses, please note them on the issue.  If I do not hear from you, we will write only a single Parquet-format output to 
.../_lakefs/logs/gc/expired_objects
 .
THANKS!
