This is a really simple question. I was just wondering if a node's Hide Value option has any effect at all when it's for an Output instead of an Input. (This is found in the Group tab when editing inside of a Group Node.)
The following screenshot was taken within the Compositor, but this exists in Material Nodes and Geometry Nodes too.
I was wondering if it's for some planned future feature, or just a vestigial UI element, or if it actually does something I'm not aware of... because I can't think of any nodes that have sliders on their output sockets.
Just curious if anyone knows. Thanks.
