Bringing back Playstation Home in VR is no brainer why haven't they done this.
It should of been a PSVR2 release title.

Creating a virtual world like PlayStation Home in VR would be a significant undertaking, requiring a substantial amount of development resources and time. It's not as simple as porting the original PlayStation Home to VR; it would require a complete reimagining of the concept.
