For instance, you say "Information which could have been captured with improving technology, if only the excavation had happened later." A not-insignificant amount of archaeology is performed because of an imminent threat to a site, be it natural (rising oceans) or man-made (highways). I recall reading about (what I consider to be) significant Roman sites in London being destroyed after examination because a developer had a building plan for that particular location.
Even Time Team would dig up mosaics in a field, record everything meticulously, present their findings to the public (in a rather unscientific manner), and then bury it again, to protect it.
Go and expand your horizons, instead of making decisions based upon incomplete information. You have some pleasant surprises waiting for you.
