Negative
At least because it just transforms your code into React Native, that's it.
So, instead of transforming garbage into "pseudo-native" mobile app, Vue Native is transforming mini-garbage into garbage first and than again garbage into mobile app.
"Let's write a dropdown in a browser in a JavaScript because it is the only language browser understands, but let's do it in TypeScript, but before that let's write in PHP and before that let's write it in Java and just transpile Java > PHP > TypeSript > JavaScript."
I can tell you a secret, you can just write an iOS app using Swift itself and you do NOT need over 9000 other steps to get to the Swift, and same for Android, you can even use Kotlin!
It's like "I wanna leave in China, but I don't wanna learn Chinese and only less 1% understands English, so I will just hire a translator who will be walking with me whole my life, la la la, cha cha cha".
So, at least until Apple, Microsoft and Google won't be providing, supporting and maintaining official JavaScript API and compiler for their native platforms...
