TLS handler does not support TLS_FALLBACK_SCSV

I know it’s not exactly the end of the world but i was wondering why the TLS handler does not seem to support TLS_FALLBACK_SCSV downgrade protection.

Is this a design choice or just something that wasn’t deemed to be important enough to implement? (To be fair, it kind of isn’t, tls 1.2 is fine)
