Nimble, really? You don't even have an all-flash product. And, if anything, one can claim your product is optimized to work with SATA HDDs, not even all types of HDDs, let alone SSDs. See where claims lead to?
You're focusing on ONTAP as is Nimble's idiom, but we have EF and ONTAP both. Mature platforms, both. Both not originally designed for flash media since it didn't exist back then. Both crazy fast with flash today.
Guess what... It's all code. Code can be changed. And it has. There is this type of creature, you see, called a developer... we have many, many of them :)
Witness the super high performance numbers produced by products that all were "originally" designed for spinning disk. NetApp, HDS, HP - all have great performance with SSDs.
And, if anything, one can argue that ONTAP is more friendly to SSDs than most architectures out there. By intention? Not really - let's call it a happy accident. But if you understand ONTAP internals is is clear that the core of it has nothing to do with spinning rust at all and it's all about data management.
Last I checked, we are in this business to solve customer problems.
And please spare me the "will never happen" arguments. I can make similar ones about your company but I will take the high road. Plus it smells a bit like roadmap-revealing bait, which I won't take.
