Just to clarify, this is only time [I/O] expensive when reading and updating the tile offsets+sizes?
Or is it also wasteful of space by duplicating the whole IFD each time I do an update?
No, there's an optimization in libtiff where it detects that only the offset +size arrays have been modified, and rewrite them in place.
Ah, brilliant, that's really great to know and certainly puts my concerns about bloating the file to rest.
