We have been here before...maybe in a different form and beat the daylights out if it. Simple question, Responsible to whom? the club, hey they are ones making the decision first to hire the architect and then to agree or not agree with their plan, the dead guy, Tom Mac & Mark Fine cover this well and I personally would agree with their approach, but the reality is that not all true classics that are being worked on by architects have architects that care, or care to take the time as Mark says. Are they responsible to history, heck, if we want to look at this way, why are not these great classics placed on the National Register of Historic Places, hell, all kinds of landmarks are so why not the priceless gems of the golden age or whatever age? Maybe if this was done, we could take the edge of this cottage industry that Mike Y. refers to...I think he has a good point, and some point soon I believe, it is all going to come to a head.
This leads us to... are they responsible to themselves? can they sleep at night and feel good about their work and about going on to another club and tell them about what they did for so and so? I couldn't, but then, I would never do it that way.
Who should the clubs listen to? Should they listen, it is THEIR club right. For that matter, a lot of clubs should be looked at more carefully. Are they classics? no, but that doesn't mean they don't deserve the responsible respect by the architect to at least do some research and inform the club of their history, assuming they may not know, and give them options as opposed to using the opportunity to leave their mark.
Mark Fine says it accurately, "I believe every course at least deserves a look at what was originally designed and how it has evolved. Clearly not all courses should be "restored" but they at least deserve this look (and the look for some courses might turn out to be much longer than for others). That is part of the responsibility of any one chartered with making changes to a golf course"
