display the value of an unconnected node output socket

I know that you can inspect the value of the output socket of a geometry node when hovering it. That's nice.

But when the node is not connected, that value is not evaluated thus not available for inspection: I guess this is made for sparing the computer ressources.

But it makes setups more difficult to debug.

Why not having a way to inspect the value of an unconnected node output socket; eg. while hovering the socket with a key pressed ?

Thanks !
