This is not a true fix, but a kind of workaround…
If you CRANK – like values 700-800+ — the light’s size, it can sort of “hide” it in reflections.
Obviously this also changes the way the light works but it’s the only way I could get around the lights showing up in everything that was reflective.
Point light for example, you could set the Source Radius, Soft Source Radius, and/or Source Length to extremely high values, and it’s still SORT of visible in reflections but it’s more subdued.
Again. Not the same as Maya’s attributes, but for me at least it was better than nothing.
