This is a great update. I'd wondered how ply differed from bpftrace. And structs support is a huge step in achieving parity with DTrace.

DTrace has really helped me out* on macOS. To be without it is to lose a superpower, so I'm really rooting for bpftrace to bring the same tracing experience to Linux. I've been excitedly following bcc, too. It's just the right tool for HTTP metrics. But my most basic experiments so far have failed, and I don't know how to get support.

* DTrace is a real swiss army-knife. It seems intended for observing production systems, but I've found it indispensible for local development. The mysqld provider is great for tracing queries and perf. Opensnoop answers all sorts of questions. And DTrace saved a C++ project of mine: explaining a deadlock that would've otherwise spelled the end of the software. The most fun I've had is using the pid provider to hook text out of visual novels (in WiNE!).

I'd recommend the #iovisor irc channel on oftc. I haven't stopped by in a bit, but the times I did, I usually was able to get assistance from nice people!
