Hi,
if I look at it this way, I have these commands too.
It saves one click compared to the yellow selection arrow.
The notation is by me
Instead of :part by me 'SELECT':PART
but this only makes sense if you want to select e.g. a cylinder.
Thus selection of the part by click on a surface.

Instead of :assembly by me 'SELECT':ASSEMBLY
That makes sense. Very convenient.

But selecting a 3D surface is what Modeling does anyway.

Can you explain why this is so good?

I hope I understood you correctly. ;-)
