I think I got your point, but it would be even better if you had a
stacktrace or a case where this check is actually invalid. Imho,>=
should still be true, even if the packing is different.


on x64, sizeof(SpiceMsgWaitForChannels) = 8 (packed 1) and sizeof(SpiceWaitForChannel) = 16 (packed 10).
< will always be true.
