Is changing OGL_DX_PRESENT_DEBUG setting really necessary? My testing shows that Prefer layered on DXGI Swapchain alone is sufficient.

Yes, as it mentions on the following line:
"This value will enable the DXGI swapchain layer in most scenarios, including DXVK."
Without that flag set, the interop layer won't engage in various scenarios (typically emulators, DXVK, and a few other cases).
