You’re right, as the medieval period progressed a lot changed. Those 1000 years were very different across space as well as time.
The conversation has also not been distinct with serf vs. peasant, which is an important distinction in conversations like this.
Thank you for the extra details and pointing out there Lords did still work to retrieve serfs.

But yes, the IAU tends to only pin down definitions when one is becoming unworkable - in this case the ever larger numbers of trans-Neptune objects that were potential planets.
