Yes, that could work for secrets storage. However we also store
persistent logs and DHCP leases on this flash to minimize read/writes
on the main flash, and this data is stored as files of varying lengths.
A filesystem provides the most straightforward way of storing this data
for us.

That's not to say we couldn't develop some system of using the nvmem
device as a backend for this data. This may be something we look at in
the future.

Thanks,
Ronan.
