[SOLVED] RP Directives?!

I have a simple question. If you are developing an asset, currently how do you differentiate between different Render Pipelines (excluding LWRP).

What I would expect is with the use of directives:

#if UNIVERSAL_RENDER_PIPELINE
private string s = "Universal";
#else
private string s = "Legacy";
#endif

However there is no such thing for the Scriptable Render Pipelines!

Right now, both Universal and High Definition HAVE to be installed, otherwise the compiler is gonna complain about some non-existent namespaces. Can this be added to Unity?

I found it on accident

#if HDRP_6_EXISTS
using UnityEngine.Experimental.Rendering.HDPipeline;
#elif HDRP_7_EXISTS
using UnityEngine.Rendering.HighDefinition;
#endif

My mistake!
