If tree hack wasn't used in the era, then like light filters, it shouldn't be used here.
While these are generally seen as small conveniences, such features give an advantage to the user, eliminate obstacles that were intentionally put into place as part of the game, and put players who use era accurate methods at a disadvantage.
Back to the topic, Einstein seemed to suggest that we should post each and every Razor feature that should be disabled so that he can nitpick it

There are a number of Razor features that I think should be disabled. Ultimately I think that third party programs endorsed and used here should only have the same functions as what were allowed during the era, but that's really not my decision to make.
The argument here is that there are some features which clearly shouldn't be endorsed on a server that strives so hard to become 100% accurate. Having a third party app (whether its Razor or a JoinUO tool) that could be required to be used, thus allowing the features to be negotiated would be a great step for better emulating the T2A experience....even if it just started with something so simple as seeing "In Lor" back ig.
