Subversion isn't ignoring them, it's just reducing them to their
smallest total effect: namely, that nothing happened. If you rename A
to new file B, and then rename B back to A, and never committed any of
it, then nothing happened. The user may have a memory of something
having happened, but how would its result be any different from the
situation that Subversion reduced it to?

If there's guessing involved, then I agree -- Subversion shouldn't
make fuzzy guesses except when you ask it to. But this isn't a guess.
What happened is clear and unambiguous. To put it another way, the
effect of each operation was fully understood by Subversion, and so
the "sum" of the operations is also fully understood. Why shouldn't
it make use of that knowledge?
