This means that systems that never had version 1.0 installed will be
different from systems that were upgraded. The point of having a package
manager is to avoid precisely this situation.
What is the actual use case? What does "fileB.txt" actually do so that
this is desired?

No, dpkg removes any files that are no longer part inside the tar file
embedded in the package (i.e. the absence of the file in the new package
is the trigger for its deletion).

Then those two packages would have had an agreement on who provides that
file (i.e. one of them declares a Replaces: relation on the other),
otherwise it would not be possible to install both packages at the same
time.
