Interesting. I was lifting for nearly ten years, did starting strength, texas method, 5/3/1, and I found that the soreness largely went away unless there was a marked change in intensity or program.
This has been my experience with a sustained period over years of lifting in my early to mid 20s and several periods of restarting since then. Even when regularly adding weight, after a few months I stopped being particularly sore.
I could still feel that I had worked out the day before, sure, but as long as I was getting enough protein, getting enough sleep, doing warm up sets, etc., the soreness was incredibly minimal. Missing any of those things could cause a pretty significant increase in feeling it the next day, though.
