Hello Felipe

Accessing current_thd->scramble would be very fragile.
You would need to build your plugin together with the server (from source=
)
because object layout in memory may change.

We have getters/setters for misc thd properties, some declared in=20
thread_pool_priv.h
others declared in service_thd_alloc.h

Alas, there is nothing to access THD::scramble.
Making one would be trivial though.
