As we discussed on IRC, this is fine for distros where the program is being used on the locally shipped X server, with a consistent support in the Xrandr client library and the local X server. (e.g. Fine in the context of a disto local patch).

For an upstream fix, they must consider the case where the X server might be remote, where it is much more likely that the client library and server extention don't match in feature-set.
