I think the problem is round-trips, so the current file-name-handler-alist operations just don't cut it. We could either put higher-level ops in there (like `save-buffer'), which implies replicating the whole `save-buffer' behavior, which is a lot of work and likely to be not 100% faithful. Or we could introduce new low-level ops that are asynchronous, and then rewrite save-buffer to use them. IOW save-buffer would start with a bunch of calls like `start-getting-file-attributes' which could immediately be passed on to the remote side, and later on checks the return value of those calls as and when needed.
