TxPool: txpool_content must not return blob txs

[AskAlexSharov]

I see geth does:

func (p *BlobPool) Content() (map[common.Address][]*types.Transaction, map[common.Address][]*types.Transaction) {
	return make(map[common.Address][]*types.Transaction), make(map[common.Address][]*types.Transaction)
}
func (p *BlobPool) ContentFrom(addr common.Address) ([]*types.Transaction, []*types.Transaction) {
	return []*types.Transaction{}, []*types.Transaction{}
}
func (p *BlobPool) Locals() []common.Address {
	return []common.Address{}
}

Seems same need for: txpool_contentFrom and txpool_locals

But does the spec say that txpool_content should not return blob txns?
