I don’t see how is that easier.
In fact, I don’t see any upsides to pruning so aggressively - neither from performance nor cost nor functional perspective. But I do see at least one massive downside: What if the corruption (to your irreplaceable family photo) occurs silently and you don’t notice it immediately, but discover, say, three months down the road? Then you don’t have a good version to restore from.
Keep long (infinite) version history. You don’t have to keep hourly snapshots of course for years, configure prune. Say, keep hourly backups for a week, daily backups for three months, and then weekly backups forever. Or just never prune. That is a valid approach as well. I don’t prune my photo collection backup. Why would I?
