It sounds like you suggest changing this "remove + copy" operation to a
simple "modify" operation on the fly if the copy is from an older
version of the same file. Is that a correct interpretation?

This is unfortunately not possible without severe performance
consequences. If there is no remove+add this means that the file id does
not change, and to prove this we would have to analyse the history of a
particular file to see if it shared history with the file it was copied
from each time we encounter a file copy.

Cheers,

Jelmer
