Details

C++ code can do variable = profiler_capture_backtrace() followed by MarkerStack::TakeBacktrace(std::move(variable)) later. It would be really nice to be able to do something similar from JS code.

I think the API would look like:
variable = ChromeUtils.captureBackTrace() followed by ChromeUtils.addProfilerMarker(name, {stack: variable}).

The current {captureStack: true} could be changed to {stack: "capture"}.

As Mike pointed out at https://phabricator.services.mozilla.com/D121887#3963071 having such an API would have been really nice for the DeferredTask markers.
