All true... While working at Colonial Williamsburg I learned the obvious... prior to central heat and A/C the interior of buildings were never consistently dry the way they are today... As such, durable goods like furniture, doors and windows were make taking seasonal wood movement into account. This by using construction techniques that allowed for movement. For example, frames with floating panels.
Something I speculated about for many decades was the notion that wood was more stable "back then" as it was old growth. I didn't accept that... I thought that what seems stable today in old furniture, doors, etc. was more a function of the wood fatiguing over time from the seasonal movement, i.e., it "lost it's life." I cannot put my fingers on the source at the moment but researchers fairly recently came to the same conclusion... decades/centuries of movement breaks the wood down so it doesn't move as much. Have you ever noticed how dead really old (100+ years) boards feel when you work them? I won't be around long for anything I've made from air dried wood to get that dead so I built to take movement into account.
