I think theres an interesting story in software ecosystems where there are two flavors of applications (which coexist) that prefer object stores over filesystems and vice versa. Good reference point for this I think exists in many modern video transcoding infrastructures.

Using something like FSx [1] gives you a performant option for the use cases when the tooling involved prefers filesystem semantics.
