Shenandoah (and ZGC for what it's worth) do work out of the box on Windows AArch64. We didn't test them extensively though and did intentionally not included them in the JEP to reduce the test surface for now.
Monica has opened a bug for both GCs: https://bugs.openjdk.java.net/browse/JDK-8252114

Good catch, they are not needed. Removed.

Apparently they aren't needed too, hu. Removed.
Tested the build on Linux AArch64 and Windows AArch64.
