Nope. It's a fairly recent code change to support in the base BOINC code. Prior to that PrimeGrid, Yoyo@Home,NFS@Home and Oproject implemented it themselves, so the base changes are pretty similar. But so far only Bitcoin and CSG have taken up the new code..
We need to push the other projects to implement it. I've asked in the past without response at some of them, though that was prior to it being incorporated in the software direct.
WCG would be the biggest candidate..but I've tried for a long time there.
