It has been unreliable in my experience.

button from the system

I've rarely, perhaps never, seen a customer have to tune the -c flag.

By disabling the power button, do you mean setting HandlePowerKey=ignore in
logind.conf? That's not specific to fence_ipmilan, to be clear.

kernel module for a watchdog device and it never failed us. Yet, it's just
a kernel module (no hardware required) and thus RH do not support such
setup.

What do you mean by triple sbd? Correct that RH doesn't support using
softdog as an sbd watchdog device. It was determined that it's not reliable
in all situations. It's probably fine much of the time, and I'm glad you
had a smooth experience with it.
