S3 is evolving rapidly. While sticking with the old MinIO image might work for the immediate short term, I believe it is not a viable strategy for the long haul.

New standards and features are emerging constantly—such as S3 over RDMA, S3 Append, cold storage tiers, and S3 vector buckets.

In at most two or three years, relying on an unmaintained version of MinIO will likely become a liability that drags down your project as your production environment evolves. Finding an actively maintained open-source alternative is a must.
