I also noticed the same thing on my v23.7.12_5 box.
I am using Unbound DNS's overrides to "create" an internal DNS domain/zone for my LAN.
I have an "Host Override" entry per server/IP and I recall I had multiple aliases in the entry (also years long setup).
Today I wanted to add a new alias and could not find where I needed to add it and hopefully I stumbled on this topic.
Here is the XML part from an OPNsense configuration backup on 2021-08 (so I guess it was v21.7, or maybe v21.1):
And later on, as JeroenS posted, the aliases were moved to another part of the Unbound configuration.
