Ah, yes, that is absolutely true.
I do recall finding that service when was investigating differences in packaging before UCA and RDO when was originally reporting issue to RDO a month ago.

Bug description:
In jammy/antelope repo openvswitch-common=3.1.0-1~cloud0 contain a
buggy version of OVS that does not respect `ovs-vsctl add` command, so
instead of appending values it does replace them.

Description: Open vSwitch common components
Open vSwitch is a production quality, multilayer, software-based,
Ethernet virtual switch. It is designed to enable massive network
automation through programmatic extension, while still supporting
standard management interfaces and protocols (e.g. NetFlow, IPFIX,
sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed
to support distribution across multiple physical servers similar to
VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.
.
openvswitch-common provides components required by both openvswitch-switch
and openvswitch-testcontroller.
N: There are 2 additional records. Please use the '-a' switch to see them.

```
This can be workarounded with setting `OPTIONS="--no-record-hostname"`
in /etc/default/openvswitch-switch
Path in OVS has been already proposed:
