Chrome actually has those stats in their "legacy" stats (dtlsCipher on 
googComponent). I find them curious but I can see how you use them to 
weed out bad crypto.

 From what I can see there (without splitting it up further between 
browser version and or/peer:

   percentage  |                dtlsciphersuite
  59           | TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
  21           | TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
   6           | TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
   5           | TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
   4           | TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
   1           | TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
   1           | TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
and things below 1%.

If that violates anyones expectations about "strong crypto" I can try 
splitting it up by local version and remote browser type.
