Yes, and that is a HUGE difference. For my use cases, Chrome's implementation is worthless, and I have used tools like WebCatalog, Coherence X, Unity, and previously Epichrome, to achieve this. The problem with these tools is they are usually 1-person operations and the maintenance is too hard (browser stuff moves fairly quickly) and they tend to get buggy and unwell after a couple years. Having standalone web apps — with their own processes, application layers, and sandboxes to prevent cookies/sessions from leaking between them — built into the OS is the most exciting macOS feature in years, IMHO.
