There are no currently planned changes to reflections other than the addition of some very limited planar reflections added for the proto star demo. That can help you get nice mirror reflections on the ground but only one reflection.
You can easily get single mirror reflections using 0 roughness materials. These will reflect screen space reflections as well as the static reflection captures you place around your level. But if you want to have that multiple bounce effect you will need to do it manually and probably just accept that characters will not have multiple reflections.
