Add Group ID input to Sample Nearest Node

Index of Nearest node has Group ID input, and in 4.2, Group ID input is about to be added to Geometry Proximity Node and Sample Nearest Surface Node.

But is it not going to be added to the Sample Nearest Node? It may be a technical problem that I am not aware of...

As an example, I would like to do something like this: I would like to make a Particle in a Simulation Zone follow the tangent of a particular Spline, and I would like to have a Group ID for that...
