At least the docstring of `with-slots' and the EIEIO manual both state:
"Both ‘setf’ and ‘setq’ can be used to set the value of the slot." In
particular, it doesn't state that `let' can be used for this purpose. So as
long as `setf' and `setq' continue working, I think it should be OK to
change the behavior (it should still be documented as incompatible Lisp
change though).
