Yes, totally agreed, but the problem is that most people tend to simplify this as "let's just bother with PQ encryption, forget about signatures". I know experts can handle the nuance, but execs and most industry folks can't. Or, at least, this is the trend that I have personally observed countless times, maybe I was just unlucky with my data points, but I have seen this in "technical" settings as well (case in point: GnuPG prioritized inclusion of PQ hybrid encryption, to the point of rushing the standard against OpenPGP, the well-known "GnuPG schism", but I'm not aware of concrete plans for PQ signature adoptions there).
