This set of patches (details below) provides a way to set or unset each of these attributes. While making policy decisions about these flags, like for ffp-contract, we have created an RFC (https://discourse.llvm.org/t/rfc-ffp-contract-default-value/66301). When adding umbrella flags like -ffast-math/-Ofast/-ffp-model/-funsafe-math-optimizations, we will submit RFCs.
