Can confirm what is described here.
However I am not sure hiding them from the viewport is actually desired here, since hiding them in the outliner doesnt really take away their influence on the render.
So this might give you the (false) impression that this cache will not contribute to the render if it is not visible.

Just my thinking, will let @fclem decide here...
[ @fclem: btw. hiding them with the effect that they actually dont contribute would be a kick-ass feature :) -- since it would allow for different cached lighting moods in a single file, not sure though how practical this is, since I guess to get this dynamic, there would need to be some shader updates happening? Also not sure how future work on irradiance volumes would come into play here...]

I was probably a little too quick to call this a bug...

To me it also seems practical as often I have Irradiance Volume in it's own collection and use the irradiance spheres visibility toggle to check stuff.

There is no connection between the probe object and the lighting data. This is because we could use a different indirect lighting solution in the future in which the data points could not be associated with one particular probe.
It is also for the sake of simplicity of the baking system. So there is no way to hide the visuals other than the indirect lighting visibility button.

So I don't consider this a bug.
