I've seen some suggesting that increased support, but even at Juniper,
actions seem to speak larger than words.  There seems to be very little
interest for awhile now.  However, I do know of some providers who use
it, largely internal only.

We also have tried a community flow-spec service, and more recently
have been prototyping a community RTBH server with flow-spec capability
(ping me off list if you want to hear more or see me at NANOG 62).

A few people have recently told me they would like our community RTBH
service via flow-spec instead of just BGP next hop, but really only one
seemed seriously intent on configuring it day one.
