No, *target unpacking (singular) is quite useful in specialized cases. But
it is not specifically head/tail unpacking.
a,*b,c = 1,2,3,4,5,6
a,b,c
(1, [2, 3, 4, 5], 6)
*a,b,c = 1,2,3,4,5
a,b,c
([1, 2, 3], 4, 5)
I personally quite like them, but I would like them to be more general.
It already is. The *target can be anywhere in the sequence.

You can even have nested sequences!
a, (b, *c), *d = 1, "two", 3, 4
