Totally reasonable. In that case, I would consider adding a
transaction ID column to each class of object and offering a new API
call that lets a client request a monotonically increasing ID. If a
client posts an edit without such an ID, the server should
automatically attach one. This way clients *can* group edits, but
aren't obliged to.
