I was talking about automatic instrumentation of every single function call by default. No manual instrumentation needed because everything is already instrumented.
To be fair, you do still want some manual instrumentation to correlate higher level things, but full trace everywhere answers most questions. You also want to be able to manually suppress calls for small functions since that can be performance relevant or distorting, but the point is “default on, manual off” over “default off, manual on”.
