I feel like 1k on the main branch is reasonable. I'm not sure, but I'd guess a lot of our cost is coming from the other 5k on feature branches.

I haven't fully thought through the implications of changing this on every ECR repo we have, but putting up a PR anyway to start a discussion.
For reference, we're spending roughly $670/mo on ECR storage in the remind AWS accounts.
To roll this out, we'll have to cut a new
v1.x.yrelease and then trigger all the CircleCI pipelines that use the orb, and they should all update the lifecycle policy for their ECR repos.
