Meta XR Core SDK Ubuntu Package Error

Will preface this with the fact I am aware Linux isn't supported or tested by Meta.

I am using Unity 6000.3.9f1 and Meta XR SDK 203.0.0. I recently tried using an Ubuntu GitHub Actions runner in a CI pipeline to deploy a Unity app to a Meta Quest 3. I encountered a strange pair of errors, which then persisted as I tried opening an empty project with just the Core XR SDK locally on a Ubuntu Linux computer.

Here are the errors in question:

Library/PackageCache/com.meta.xr.sdk.core@f4a2a776f923/Scripts/RuntimeOptimizer/Core/RuntimeOptimizerPlugin.cs(29,2): error CS1032: Cannot define/undefine preprocessor symbols after first token in file
Library/PackageCache/com.meta.xr.sdk.core@f4a2a776f923/Scripts/RuntimeOptimizer/Core/RuntimeOptimizerPlugin.cs(33,2): error CS1032: Cannot define/undefine preprocessor symbols after first token in file

Doing some more investigation, I found this in /Packages/Meta XR Core SDK/Scripts/RuntimeOptimizer/Core/RuntimeOptimizerPlugin.cs.

It would seem that being on Linux deliberately causes a pair of #define lines to be run, which triggers an error in the C# compiler (preprocessor symbols must be defined before any code, including 'using' directives).

Has anyone found a fix or workaround to this? Is it possible this script could be changed in future versions that wouldn't break or interfere with any other functionality?
