Review comment:
See
https://github.com/apache/arrow/blob/maint-0.17.x/cpp/src/arrow/ipc/message.cc#L57
So it only checks for old versions but new versions pass silently, which is
quite scary to me. But on the other hand the risk of V5 data breaking a V4
application (e.g. Spark) at the moment is low.
