Weex was adopted by the Apache Foundation, so it has already found an "official" OSS home. We will of course continue to collaborate and support their development and integration with Vue, but won't make this an official solution inside of the vuejs organisation.
Concerning Nativescript, to be honest I don't think we had time to discuss this in-depth. For now, we will let the community work on this and improve it. If it makes sense to integrate in in the future (and if the creator is willing), that is a possibility, but not on our todo-list.
We are also not actively planning to come up with a solution for native implementation of our own, that's not where our core compentence is right now, at least from what I can tell about our teams strenghts.
Personal opinion about the name suggestion: it's not clear how to pronounce it, so it probably would not get my vote. ;)
