...ay violate the IEEE 754 standard and the OpenCL numerical compliance requirements for single precision and double precision floating-point, as well as floating point edge case behavior. This option also relaxes the precision of commonly used math functions. This option causes the preprocessor macro __FAST_RELAXED_MATH__ to be defined in the OpenCL program. The original and modified values are defined in the SPIR-V OpenCL environment specification I'd like to emphasise in the latter one: "This option also relaxes the precision of commonly used math functions."

I'm not aware of any additional bits needed. But putting us right at the edge leaves me uncomfortable. So an implementation that isn't limited by the 7 bits in SubclassOptionalData seems sensible.
