FYI, I believe the last iteration on this topic ended with this message:

i.e. consensus that base64 should stay out of the Encoding API, but that it
would be nice to have some form of base64 / Typed Array conversion API. But
there were no concrete proposals beyond my strawman in that post.

So: agreed, have at it!
