Yes they are. Read this. It's right at the top.
<a href="https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#features-formats-compatible-planes">https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#features-formats-compatible-planes</a>

It's a solution, though not the one I want, is recommended by the spec or
something I'd like to waste time just to find out it doesn't work.

That would explain why it doesn't work.

I am running it through validation layers every time and I've reported all of
the issues on multiplane images, including the one where they don't list R8 and
G8_B8_R8 as compatible. It'll get fixed.
Though considering how many assertions have been made in the validation layers
that no one will ever bother with multiplane images I'm getting tired. Though
the fact that they're slowly getting fixed one at a time gives me hope.</pre>
