Well, if you are asking for opinions, my opinion is that this thread is MOST DEFINITELY ON TOPIC. In my view anything that pertains to collecting, restoring, maintaining and riding classic bicycles is on topic here. The mere fact that the same techniques might also be applied to off topic bikes is completely irrevelant. Classic bikes In The Day required the prep discussed, and one still finds clssic bikes today that were never properly prepped, and so need the measures discussed in this thread. If we are going to ban any discussion that might possibly be relevant to newer bikes as well as classic ones, we aren't going to have much to discuss.
But of course my opinion isn't of much value, and neither is yours. Dale's is the only opinion that really matters.
