  Following the recent work of Henneaux and Troessaert, which revisits the
problem of spacetime symmetries at spatial infinity, we analyze this problem
using the Bondi metric without determinant condition as our starting point. It
turns out that in this case the symmetries at spatial infinity form the BMS
symmetry appended with an additional infinite set of abelian symmetries. We
furthermore find that imposing the determinant condition to the Bondi metric
would result in a drastic reduction of symmetries, with no spatial (super)
translations present.
