Could you give an example?
All changes are represented by operations, each operations is defined by
an ODF XML change. I can not see the problem scenario you draft.

So, while what an implementation does for equivalent changes is certainly up to the implementation, there are consequences, in interchange and in subsequent revision and review work, even by the same author.  There are also (limited) consequences in how changes are annotated and identified in terms of author, date-time, and any commentary.
Rejecting a change is similar to taking out an operation out of the
operation stack. No side affects, no harms.
A reject goes like this: The operation (or set of operations) to be
rejected are being moved to the top of the stack (to apply OT to their
positions), than removed.

No problem AFAIK.

This is absolutely an implementation detail of the application, all we have to care about is that similar changes are able to be reflected by different set(s) of operations, which all have in common that they have the same information set, resulting in the end into an equal change.
