Yes and no!
I'm possibly a few years older than you and can go back to tying your hair onto the hook.
I think that the knotless knot was a late 1990's idea, (I could be wrong) as until around 1994 I was tying hairs on with mono, whipping thread or dental floss, and using either biro, shrink or silicone tubing to keep the hair to the shank, and extend the hook shank.
Personally I found that on some lakes or fish, a standard knotless knot rig could be ejected, but add a line aligner and the fish would be hooked. This was watching the fish at close range, seeing the pick up with the knotless knot and watching the hook and bait get blown out.
The change to the line aligner put the same fish I had seen eject the rig on the bank. Instead of ejecting it, they couldn't deal with it and ran.
If everyone is fishing the same rig, same length, or even same material hooklink then the fish will 'learn' how to deal with it.
Add in how you feed, your baiting situation and you can change things in your favour.
There are definitely times when you need something different from the normal. Pressured fish, particular spots or how you bait up may need you to change your rig.
