Hi!
We definitely want to do this until the v4 release (which is planned a few months from now). Hopefully, we'll even manage to get in the VDB support, but that's more complicated.
I can't make any definite promises, but I think that we could add the procedural volumetric noise feature in a few weeks into one of the v4 daily builds. I added this into the roadmap (which needs to be updated, too). Feel free to ask again in a few weeks if this isn't added.
