Our embedder has a custom v8::Platform implementation. In V8 10.6, the v8::Platform::GetPageAllocator method is abstract, and no information is provided about how to implement it.
We're currently delegating GetPageAllocator to an instance of the default platform (created via v8::platform::NewDefaultPlatform). That seems to work but feels hacky. Before this we never had any reason to create a default platform instance.
Is this an oversight? Most v8::Platform methods are relatively mundane – task scheduling, raw memory allocation, etc. – whereas v8::PageAllocator is quite esoteric, and many embedders would probably not know how to implement it.
