I think that level of nitpicking is silly.
There are all sorts of places which by these standards would "historically flawed" which I think none the less make contributions which are as important if not more so than some of the others.
An Example:
Clark's Trading Post- Lincoln, NH- basically an excellent demonstration of a 19th century New Hampshire Logging railroad, which in addition to having 4 native New Hampshire steam locomotives from local logging RRs has a plethora of other preserved logging and various other equipment, ranging from steam "donkey" engines, to Lynn half tracked vehicles, to the world's only operating example of a Lombard Steam Log Hauler, and all housed within an amusement park on the theme of trained bears.
Being someone interested in these things, I think in the rare instance that some of the same equipment, trackage and structures that can be found in some photos from 1920 are still available to visit and perhaps even ride behind, is fascinating (like say the EBT). However, the harsh reality is, there are precious few places such things occur. While we are sitting here getting all excited about this, unfortunately, people in the "real world" are taking what used to be these "historic" sites and building DB Marts.
