For image registry...probably not that much. But it is quite common for other software, often those that target containers/k8s/... I already have few of those and that would be quite handy to have some good local s3.
I use mine primarily for long-term stores for Grafana's Mimir and Loki products.
Anyway, minio & garage are both lightweight, and happily run in docker, so if you've got a small cluster at home it would take maybe an hour or two to install them both from scratch.
