Your link shows all the clients you’re blocking. Expand the “unsupported clients” section. You’re currently blocking a lot of clients some folks care about (I say good riddance to them, but not everyone can).
DROWN shows that merely supporting SSLv2 is a threat to modern servers and clients. It allows an attacker to decrypt modern TLS connections between up-to-date clients and servers by sending probes to a server that supports SSLv2 and uses the same private key.

I posit there's no reason to support TLS 1.1 on your server. There are very few clients that support TLS 1.1, but not TLS 1.2. So, either you are willing to support clients on TLS 1.0 (or SSLv3), or you aren't.
You don’t “fail” due to lack of 1.1, you can still get an A+ as evidenced by Pete’s link. That said, you’ll notice that his server is blocking a bunch of clients that maybe you care about.
Not bragging, just curious where you fall down.
