  In this brief note, we show that the residual symmetries that arise in the
analysis of the tensionless superstrings in the equivalent of the conformal
gauge is (a trivial extension of) the recently discovered 3d Super
Bondi-Metzner-Sachs algebra, discussed in the context of asymptotic symmetries
of 3d Supergravity in flat-spacetimes. This helps us uncover a limiting
approach to the construction of the tensionless superstring from the point of
view of the worldsheet, analogous to the one we had adopted earlier for the
closed tensionless bosonic string.
