Headers first loading allows the node to run SPV from the very first =
minutes and it can converge to full node by time.
This is BTW how newest versions of BOP can work.
Pruning however disqualifies the node as a source for bootstrapping an =
other full node.=20
BTW, did we already agree on the service bits for an archive node?
