No, I didn't say that, nor was there any evidence of this. The developer in various dilutions easily lasted an hour. There are reports (not confirmed by me) of stand sessions going much longer than this.
Our ancestors used films or plates that had thicker emulsions making stand a more viable technique. Back in the day (say, in the Super XX era), there are stories of commercial labs doing dunk agitation and then leaving the film to sit overnight in tanks for so-called "complete development".
It is my sense that the developer is not the constraint here. Modern films are, and they are best served by Semistand or EMA. Stand appears to be a highly variable crap shoot with these films and offers nothing Semistand or EMA don't as best as I could tell
