Your comment seems a bit cynical or agenda based, but there are already many groups looking into this. i.e.

It isn't these researchers job to distinguish every phenotype of long covid as there are other groups trying to figure that out. When those definitions are clearer, I'm sure more upcoming literature will distinguish that. But for now, the current definition are symptom/observational based as we have no biomarker or means to distinguish post-vaccination / infection based long covid yet.
