No, it's not intentional.
the HAproxy is a part of services that redundant router would
enable/disabled according to the MASTER/BACKUP status. All the services
related to redundant router are controlled by services.sh.
What's the failure of HAproxy exactly in your case? And what's the root
cause?

Hi Roeland,
I would write a design doc to explain how redundant router works currently. For

It's a design
It's a design choice, the only reason is it would be a very complex
situation to deal with. In fact the redundant router itself's policy has
already been very complex...
We didn't look into details at the time of implementing redundant router,
