Unfortunately, one of the downsides of the XRP Ledger's design is that wallets are "heavy" and impose costs on all system users. There are significant advantages in exchange for this, but I don't see the reserve being likely to drop soon. XRPL has great scaling features for transaction volume and great security features for payments, but it doesn't have great account scaling. The community has continued to be conservative on this front and not risk network stability for a false appearance of scalability.
