Based on https://community.qualys.com/thread/12169
https://www.ssllabs.com/ssltest/analyze.html?d=google.com&s=173.194.46.17
and https://www.imperialviolet.org/2013/10/07/chacha20.html
I'd say "today" for CHACHA20_POLY1305_SHA256 on popular site and any
browser (including developer/nightly builds), before end of the year
for mainstream browser.

That's TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 not
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256, but close enough....
