Little, seemingly. As a historical observation, MD5 was long considered
dying, with even demonstrated breaks as far back as 2005. Yet nobody
much moved, they all grazed on happily.
Until RabbitSSL was sent running off a cliff...
However, when NIST announced that for its government customers, only
2048 bits was considered good enough, they all moved! Very fast. Even
the shepherds woke up and started running... Given that the need was
entirely for one customer for one specious and not-us attack, it is a
surprise that anyone cared .. but *everyone* moved as if this was the
most dire threat to all.
Meanwhile, SHA2 support is still spotty and SHA1 is still in use, even
tho there is a cloud over it.
Herd behaviour. Call it lemmings if you like. Observed, and repeat.
What hope is there?
