Non-standard prefix filtering by requiring "/"

How does encryption relate to file names as described in this code comment? Specifically, the requiring of / breaks the S3-compatibility of Kopia’s repository indexing as objects are prefixed n.

If performance is the primary design goal, could a change to standard S3 behavior be considered for the gateway-st, given that performance and scalability of those gateways is less a concern for Storj Labs and more on the host?
