For a split reductive group $G$ over a finite field, we show that the intersection (cohomology) motive of the moduli stack of iterated
$G$-shtukas with bounded modification and level structure is defined independently of the standard conjectures on motivic
$t$-structures on triangulated categories of motives. This is in accordance with general expectations on the independence of
$\ell$ in the Langlands correspondence for function fields.
