 potentially very negative.

 Low-level instrumentation is indeed something that once added it has to be
 considered long live thus quite stable. I don't see that as negative
 because it's useful and as long as we think correctly about which event we
 add, it should be fine. The pros are beating the cons imo. It will become
 an external "ABI/API" like our control port.

 Not sure to understand here. LTTng has indeed pretty documentation on
 their website but it's first and foremost a tracer that can be hooked to
 those instrumentation event we'll add, not baked into tor.
