Archive node implies non-pruned and txindex enabled?

One thing that made me laugh regarding the Ethereum “archival node” semantics debate was that equivalent functionality (immediate lookup of any transaction by address) in Bitcoin requires an additional index, like ElectrumX. Apparently many of the loudest Bitcoiners would benefit from understanding the distinction between a block explorer and a full node.

no, txindex doesn't do anything network visible at all. It's just a wallet-ish feature.
