What problem does this feature solve?

Run Vue JSX Directly In Browser WithOut Compile.

What does the proposed API look like?

I Want Do JSX Live Coding With Hot Reload. (I Don't Want Build Or SetUp WebPack Build Environment Or Compile TypeScript).

JSX needs a build step one way or another.

We Should Load Babel Directlly In The Browser First. And Then Translate Vue JSX Code In The RunTime. Some People Don't Really Need Build Step Actually.

Well you can load babel into the browser today.

We don't see a big enough use case for this to do any work in that direction, though.
