Note that if your server does not support formally obsolete protocol
versions, TLS_FALLBACK_SCSV support is a no-op.

Otherwise, you're making real-world tradeoffs, and I think
TLS_FALLBACK_SCSV is a reasonable one to make (with minimal server-side
logic to achieve the objective), not "punishment".
