I'm so aggravated by YT's idiotic decision because I agree 100% with the usage pattern you describe. Over the years, that is exactly what I've done many, many times.
Sure, I also watch random videos here and there from channels I never ever come back to. But if I ever want to look at the entirety of someone's uploaded videos and sort them by anything at all, it's always by "oldest first". The remaining two options are useful, too, for sure. But I've never actively sorted anything by popularity manually. Always "oldest first".
