Yes that's true. East Coast had RSA with Howrah Hatia, why not resume that as well? HWH PURI can have RSA with Gitanjali. I said ER because we have some good night time trains that can be RSA partners like Padatik etc that can be suitable for RSA with Amaravati etc. When that happens it will become a full fledged ER train, like SDAH PURI Duronto.
