[BUG] OpenUPM Broken

[TyelorD]

What happened?

If you import the package into a Unity Project via OpenUPM, then all of the code is kept from compiling due to the preprocessor macros used.

If I import the .unitypackage directly into my project it works fine, but for some reason when imported through OpenUPM the assembly thinks that UNITY_2019_3_OR_NEWER is undefined.

Is it actually necessary to wrap the code with this preprocessor macro? If so, how do we go about getting the code to actually compile when imported through OpenUPM in a way that isn't wonky or hacky?

Package Version
