HA is not a practical use-case (by itself) for RAC. If HA is their requirement, they should use Data Guard.

Performance scalability is the practical use-case for RAC. Your customer has self-selected themselves out of that use-case, but apparently they'd rather spend more money, time, and effort to get to the same place. C'est la vie...
