Is it on the roadmap to get the devtools-protocol Profiler supported?

I was trying to gather coverage data from the js code and was wondering what the likelihood of Hermes ever natively supporting instrumentation (via Profiler.startPreciseCoverage). I don't know much about Hermes internals, but I know c++ code can be covered with gcov and I assume sourcemaps are already heavily used to trace the c back to js/ts in the various other devtools that can see the names of executed function. So 🤞it's coming one day!

It is not currently on our roadmap. However things like this are driven by React Native - if they decide that they and/or their users need it, and it fits in their strategy, they request it from us and then we collectively figure out what to do.
