Summary: Floating-point CSRs should be accessible even when F extension is not enabled. But pseudo instructions that access floating point CSRs still require the F extension. GNU tools already implement this behavior. RISC-V spec is pending update to reflect this behavior and to extend it to pseudo instructions that access floating point CSRs.
