If you’re dual stack, your OS will prefer IPv4 to ULA and ULA won’t be used at all, and so the extra config overhead of deploying ULA is pointless.

Also, Linux/glibc will prefer ULAs if you have a ULA assigned to the machine, and so will anything using the update to RFC 6724. So "ULA won't be used at all" is definitely not correct.
