Sure, you're right but in all my commits, signed-off-by and
other places where my email appears, I spell Hervé as "Herve"
So, to be consistent and avoid future confusion, I prefer
to keep Herve here.

You have only one possibility, so oneOf is not needed. Unless you
already predict it will grow with new incompatible lists?

No need for line break. It's not helping in readability.

No new compatible planned right now. So, oneOf will be removed
in the v2 series.
