It looks like Harvard has a very good PR department. The relation between memory, symmetries and infrared sectors were noted a long time ago in mathematical GR, especially by Ashtekar. High-energy folks simply ignored this; and now credit everything to Strominger. ¯\_(ツ)_/¯ Since I’m a scientist, I’ll cite my sources (note the dates) 1) A. Ashtekar, Asymptotic quantization of the gravitational field, Phys. Rev. Lett. 46 (1981) 573. 2) A. Ashtekar and K. S. Narain, Infrared Problems in Quantum Field Theory and Penrose’s Null Infinity, Syracuse University Report, Presented at the VIth International Conference on Mathematical Physics (1981). 3) A. Ashtekar, Asymptotic Quantization: Based On 1984 Naples Lectures, Monographs and Textbooks in Physical Science. Bibliopolis, Naples, Italy, 1987. 4) E. T. Newman and R. Penrose, Note on the Bondi-Metzner-Sachs Group, J. Math. Phys. 7 (1966) 863.
