No, it's not a bug, but I do not agree for using arguments like "someone
did it, so I can do the same". Why did you pick up exactly this example
instead of others who removed the clock number?

I said that this is not a binding. Don't add to the binding things which
are not a binding.
I don't care how do you implement in drivers - there are several ways
how to achieve it.
