Welcome to the forum @f18m
If you’re talking to the user community, it’s something you should do to stop verification errors.
I don’t use Glacier, but I think backup-test-percentage=0 backup-test-samples=0 is a nice way.
Sometimes you’ll see no-backend-verification used, but it turns off verification by file listing too.
You’ll also have to give up on running compact which reclaims wasted space as files age away.
Turning no-auto-compact on should do that, but then space usage will just continue to increase.
Amazon Glacier Best Practices? has some other discussion. I also see some code work for this, however I’m not sure how it handles space usage and potentially constant shifts to/from Glacier.
