Not having to work around the limitations of 32-bit addressing is a convenience, but the industry has produced 4+ TB SSDs with 4+ GB of DRAM for quite a while now without this core.
The real demand for a core like this in SSD controllers comes from doing more computationally expensive work on the SSD controller than just providing a block storage device abstraction. Stuff like embedding a full key-value database on the SSD or providing more general-purpose compute capability is a hot topic for enterprise storage. There's already at least one company shipping an SSD controller for computational storage with a mix of realtime cores and Cortex-A53 cores. The Cortex-R82 means such a chip could be more homogeneous with just one type of ARM core.
