My own experience is that increasing "failover redundancy", which adds
correspondingly increasing complexity, also increases the odds of an outage.

It is very rare that failover redundancy works as intended during an
actual failover, no matter how many times you simulate it.

I would rather have a simple network design where the cause of failure,
when it happens, is obvious and quickly corrected. For example, I would
rather have replacement parts on the shelf and be able to slap them in
quickly than be running hot standbys and paying for the electricity, and
then have the thing break anyway when there's a failure.
