I’ve seen overengineered and undermaintained HA systems result in much lower uptimes than a simple system with multiple SPOFs. I’ve seen well built and maintained HA systems fail under “rare” edge cases.
I’ve also seen well built and maintained HA systems work exactly as desired.
As a general rule, the cost of building and operating a reliable HA solution is not 2x, but at least 10x. If the system being protected is not worth that, you’ll very likely find the MTTR acronym far easier to catch than the rather more slippery HA.
