Agreed.

In general I am in support of having the SoC information exposed
somewhere. I think we just want to be careful that it doesn't become a
dumping ground for anything and everything SoC related whether the
information is useful or not. I think each piece of exposed information
should have a genuine use case, not just "because we can".
