Being able to select envmapbake components is great! But I'll note that in the envmap reactor you removed the Default case functionality where, when no texture/bake is assigned, an envmapbake component that the envmap component is inside the box of is automatically assigned. This means that all scenes that were sampling bpcem envmaps this way are broken and must be updated, including the apartment and my demo in the test suite.
