I’d also reiterate how frustrating statement is.
This implies that if it isn’t contradicted it holds true. There’s so much historical tidbits that simply aren’t available anymore. Just two that were brought up recently are needing the be able to stand next to and physically “touch” the Wayspot (please

Without these published or even currently posted and quoteable we lose out on ability to share that knowledge and creates unnecessary community dissent.
