Well, I do not have a strong opinion.  And indeed the symmetry looks
nice.  However, just to be sure: what’s the use case?  Because


    $(guix time-machine -q --commit=9a2ddcc8f5a6f64b475eeb13a3f1034aa6a4a49a)/bin/guix describe

is equivalent to:

    guix time-machine -q --commit=9a2ddcc8f5a6f64b475eeb13a3f1034aa6a4a49a -- describe


Cheers,
simon
