Ooohh, so snap to center of object is meant to be used when the rotation center has been moved? Hhmm....
"rotation origin" would be an improvement - not sure about solution, but definite improvement
For snap to center of object, could tooltip be "snap to center of object if rotation origin has been moved" ? It's a bit long, but much less confusing.
I don't suppose Inkscape can identify when the rotation center has been moved, and then fallback to snap to center? Too much ai?
But as Maren has clarified, is the fact that you can't snap to the center of objects in a group, using snap to rotation center, a bug?
I also just now discovered that you can only snap to the center of a text object using snap to rotation center. Snap to object will not snap to the center of text. Or the center of imported raster image either. Moving the rotation center has no effect. It still won't snap.
Should I make a bug report?
All best, brynn

Hi Friends, Here's the setup. Snap the center of one object of a group (of 2 or more objects) to the center of a rectangle.
If you use the option "Snap an item's rotation center", it won't work.Inkscape wants to snap the center of the group to the center of the rectangle.
I think this work as intended, as far as I can tell. It can be confusing though. Inkscape tries to snap the ROTATION center of the group to the ROTATION center of the rectangle. This rotation center of the group however does not coincide with the center of the object, so snapping likely occurs on a different position than you might have expected.
Questions:1 -- Is there a bug involved in the above scenario?
I think it works as it should.
2 -- Exactly what is the purpose for "Snap center of objects" compared to "Snap an item's rotation center"?
When creating technical drawings, it can be very useful to rotate one object around some point on another object, or around the intersection of two guide lines, or whatever. In that case, the rotation center of the object is moved (snapped) to that other point, and hence it is located far away from the center of the object itself. To still allow snapping to the center of the object, one cannot use the rotation center anymore, as this is located far away. In such a situation one can use snapping to the center of the object, instead of snapping to the rotation center.
3 -- Could the tootip text (for one or both options) be improved, to better represent how they work?
I'm guessing that the main problem is the subtle difference between the "rotation center" and the "object center". Maybe it would be good to rename the "rotation center" to "rotation origin"? If we remove the "center" part of "rotation center", then it's no longer implicitly in the center of the object. Even better would be "transformation origin", as it is also used for skewing. But this might be too technical, I don't know. Anyway, it would have to be changed in more places than only in the tooltip, likely.
