Another fork that will die within 5 years, why they not adopt it into directly into normal browser is beyond me. Not much users use VR on a daily system anyway to experience the web trough it. That is maybe 1 percent of their entire user base.
Merge the code, reduce the clutter from this version and make it accessible trough the actual stable ring, so you do not need to depend on another project and everyone can decide to use and enable it or not.

Because it would add a lot of bloat nobody needs and FF already takes years to compile.

Thats a very optimistic guess, I’m pretty sure that there are like 200 people, not including the developers, who ever used this.
