Tom MacWood,
I think the area you have difficulty understanding is the independent, self governing, self driven nature of individual golf clubs.
There isn't a governing body or a loose confederation that influences individual clubs when it comes to how they adjudicate internal issues.
There's the managers association, the superintendents association, etc., etc.., but, when it comes to running a club, each club has its unique modis operendi, its own culture.
And as such, it's difficult to impart wisdom, guidance or influence where the rubber meets the road.
I always felt that the USGA could have been a powerful influence in the architectural arena, springboarding off of their agronomic consultancy role.
But, where to start ?
I'd opt for clubs that have a historical connection to the USGA vis a vis tournament venues.
If the USGA had the department you seek, to offer historical architectural information, guidance and advice in conjunction with their turm management service, I think clubs would be well served, and that courses would be protected and restorations more likely to take shape.
However, there's an inherent conflict.
Course set ups for National Championships versus course set ups for daily membership play.
Resolving that issue would better position the USGA to offer the kind of consultancy you seek.
