In my opinion this is too vague - as long as CAs will issue SHA1 certs 
(and there is still a very high demand for it) others are forced to do 
the same. I suggest that there should be a fixed date(s) that defines 
when a certificate can't be issued anymore with a SHA1 hash.

In the end those that chose to refuse SHA1 certs will lose again when in 
2017 there are still X% of SHA1 certs out there and because of that the 
sunset date will be extended. We've seen it already multiple times and 
as long there is no set date it will not happen and all the rest above 
not relevant at all. Even when they'll become prohibited there will be 
CAs that will issue them (we've seen that too)...
