Looking good!

very L: should we add a version availability note? I don't see us doing that a lot around the docs anyways so feel free to ignore.

should we add a version availability note? I don't see us doing that a lot around the docs anyways so feel free to ignore.

I thought about it but wanted to get the teams perspective on this, since this is a new pattern we would follow (at least I haven't seen it that yet in the docs). But overall I would highly vote for this
