Yes. In fact, there's currently a port of the P-FP plugin with the PCP implementation to the main version in progress. It should be ready a few days.

Why wouldn't the SRP support self-suspensions? Is our implementation buggy? I vaguely recall fixing a bug related to the SRP and self-suspensions years ago.
