Description

I believe there are scenarios where users of the chainHead group of functions might benefit from querying the header of the genesis block or, at least, its state root hash. As per my understanding of the current specification, this doesn't seem possible.

@tomaka, would it be accurate to say that if a "server" supports the chainHead suite of functions, it should inherently be capable of providing the genesis state root hash?

Research direction

Start by reviewing the chainHead functions in the current specification and the question about querying the genesis block header or state root hash. Determine whether the specification should define a capability or method for this, and confirm the expected behavior before proposing a change.
