Feedback Set a #define / Compiler Directive when in Debug or Release Script Compilation Optimization Modes

I've got an interesting use case for when I set Unity in Debug or Release Script Compilation Code Optimization modes. I know I can check it at runtime using:

Code (CSharp):

1. UnityEditor.Compilation.CompilationPipeline.codeOptimization

But it'd be great if changing modes set a compilation define like UNITY_EDITOR, but in this case perhaps something like:

"CODE_OPTIMIZATION_DEBUG" and / or "CODE_OPTIMIZATION_RELEASE"

I assume it doesn't already set a define already that I'm yet to come across and is this impossible to add to the editor?

 

Given the new Beta and Alpha versions of Unity still don't provide symbols for this use case, I created a package which automatically sets some symbols related to the 'CompilationPipeline.codeOptimization' mode set in the Editor.

GitHub: https://github.com/AlkimeeGames/CodeOptimizationSymbols
Also available on OpenUPM: https://openupm.com/packages/com.alkimeegames.codeoptimizationsymbols/

Essentially, when the following modes are active in the editor, the tool automatically sets the following symbols:

• Debug Mode introduces the "UNITY_EDITOR_DEBUG" symbol.
• Release Mode introduces the "UNITY_EDITOR_RELEASE" symbol.

It does this when the Editor loads, when switching platforms - and removes the symbols during builds and when you exit the editor. It's careful not to remove any previously set symbols and doesn't interfere with any of built-in Unity symbols.

I'll also create an AssetStore asset if anyone is interested.
