Question for the Group

I know that TPRS has been used for years to help teachers comply with a pre-formulated list of words/structures or thematic units, but has it gotten to where stories are being used not to teach even grammar items? I have heard that there are real people out there teaching TPRS teachers (and calling it TPRS) how to use stories to “teach the subjunctive” or providing TPRS materials that “teach object pronouns”. This is very interesting to me. Is this true? Can someone address this in detail? When it got started? Who started it? Why?
