I'm not keen on the name 'hot standby', I find that confusing.
I would expect the 'hot standby' mode to be the one where there is a 'hot spare' connection maintained the whole time, not when the connection is 'cold' except when the primary is down.
I would prefer that the field was renamed to be more descriptive to how the connection will behave, and the description could include something like For OpenMedia Hot Standby to make it clear it should be used with this
…tStandby to openMediaHotStandby

I think it would be nice if we grouped these out-of-spec behavior flags into some sort of an options object.

Does this mean that this PR is not mergable yet? Because there needs to be an update to mos-connection before?

Yes, it appears so.
The PR Sofie-Automation/sofie-mos-connection#105 has been merged in that repository, but v4.2.0 has only been half created, so cannot be referenced here yet.
It sounds like there are some more changes waiting in mos-connection

That was the PR, but there are some additional fixes without a PR yet

Current Behavior
Currently the Primary and Secondary MOS connection are expected to be online at the same time.
New Behavior
OpenMedia treats the Secondary server as a Hot Standby, so it's not connected while Primary server is connected.
To handle this, a "Hot Spare" option is added in settings to the Secondary server.
When hot spare is activated, status messages are:
Testing Instructions
Connect MOS gateway to a 2 server OpenMedia setup.
Time Frame
We intend to finish the development on this feature in two weeks time.
