Yes, and this is less than optimal. For example, there’re lots of variables
holding a list and added to/removed from frequently.
A straightforward implementation would need to print/read the whole list
every time.
A cleverer object store would be able to figure out which CONS changed exactly,
and store a single record like 
(rplacd *id-of-the-cons* `(*new-element* . ,(object *id-of-old-tail*)))

That’s not really relevant. resist!.el persist every kv-put operation immediately
without the need of any explicit save operation.
It might be a good idea to run compact-kv-store to save disk space in idle timer, though.
