This not new.... PBBA already exists since years ago
Unitrends has been doing specialized PBBA (Purpose Built Backup Appliances) for years and can backup more than just VMware. Unitrends appliances can backup 3 hypervisors VMware, Hyper-V, Xen and over 40 guestos or physical servers at agent-based backup, including of course global deduplication, replication, instant recovery for test/dev purposes, etc
On large enterprises you need to both agent-based and hypervisor based backups:

"It's technology eliminates tape by letting people archive to public cloud"
Unitrends supports both archive to cloud and tape. Why do you want to eliminate tape? there are still some uses cases for it at some companies.
Veeam started years ago with the same only-virtualization vmware approach and had to add later tape and endpoint support due to customers requesting it and competition.
