This just wrap the code within if (!get_global_DD_EXPERIMENTAL_APPSEC_STANDALONE_ENABLED()) {

I think by the way ddtrace is currently designed, the root span will (almost?) always be the first span.
But that's more by coincidence that the root span just happens to be the last span closed - and spans are serialized in reverse order.
This may or may not change in future via normal refactors. (?)
We should at least note somewhere that we rely on that being the case now.

Ok. How would you go approach this then? I'm ok to implement it properly if it does not require any major refactoring

I'm not suggesting to actually change it, but primarily to document that you rely on this now.

I suppose it doesn't matter if there's a possible race condition where two requests hit this at the same time. The worst which will happen is that rarely two traces are sent.
(Otherwise one could do a cmpxchg here.)
This reverts commit 43eb5af.
