I think I just hit just issue as a limitation which would make s3fs useless at this time for docker stacks.

When deploying stack swarm volume names are automatically prepended with the stack name. As seperator a '_' is used and that is not allowed as bucket name.

having the same issue on docker swarm stack volumes since they are prepended with stackname including a _ character getting the error
create Weblate_postgres-data: VolumeDriver.Create: docker-legacy: Create: Weblate_postgres-data: failed: error creating s3 bucket

Yep, I've just hit this as well. S3FS plugin is currently useless for swarm stacks because of the above reasons.

As a workaround, you can define a custom volume name as outlined here, but you will lose stack scoping (the volume name is used as is).

Has anyone made progress on this? I just ran into this issue. Doesn't seem like a very difficult PR, happy to do it if nobody has done so yet.
