There is a public alliance, announced back in April: Vates joined Everpure's Technology Alliance Program, and Everpure came in as an associate member of the Vates Alliance Network (https://vates.tech/blog/vates-joins-the-everpure-technology-alliance-program/).
What that post actually commits to is validated reference architectures and compatibility documentation, with backup, disaster recovery and automation workflows named as planned expansion, so the area you're asking about is at least in scope.
Whether any of that becomes an equivalent of the VMware pure-plugin, with per-VM restore from SafeMode snapshots, I genuinely don't know, and I'd rather not guess while you're deciding whether to spend weeks on it.
Before you go far it might be worth a mention to @Team-Storage, since they'd know whether the array-side work is heading that way.
Selfishly I'd rather you asked first than quietly built something that ends up overlapping. I'm not close enough to the storage roadmap to give you a straight yes or no.
