Oomis, I concur with golfer; you are one of, if not the, most polite and respectful posters in this forum.
If your issue is waiting for an answer from one prospective until going out with another, I agree that that’s pointless. I think those who don’t go out until someone finishes working on a shiduch for them are being silly (if I’m understanding the scenario correctly).
But this has nothing to do with dating in a tzniusdik way.
Your experience, that the shidduchim process has become more conservative, is true within your framework, but in a broader historical sense, the yeshivish way is still far more liberal than how they did it in “the heim”.
