My point is, if maintaining the accuracy of the local time of historical
timestamps were a common need, someone would have designed a system that
actually does this, rather than merely pretending to do it only when a
file is never moved (geographically) from its original location.

And the cost of serving this imagined need - up front rather than only
for people to go looking for it - is unbounded bloat in the timezone
selection list.
