I would appreciate if Moog would re-invent their traditional sound using modern production technologies. I don't believe that it takes components, which are rare today, to achieve this "moogish-sound". AFAIK Moog has always explained the discontinuation of models by running out of components.
There are reasons, why the basic concept of the Model-D has become the standard for many VST instruments, which don't even try to create a moogish sound. There is also a reason, why so many developers, be it hardware or software, tried and try to get this Moog-sound right. IMO it was not the Moog brand driving their efforts ... it was the Moog-sound, which is wanted by many musicians. Maybe Bob Moog just happened to have had the luck to develop electronic designs, which create melodious sounds, which many people just like. This is worth to be continued.
Let's jump to another instrument to make my point clear and ask, which player of a violine would complain, if we could today rebuilt a Stradivarius, a Guarneri, an Amati for decent money? I think only those, who have invested a fortune to buy one of the rare master pieces. But why shall quality of sound only be reserved for the wealthy?
This said, why not invent new creative tools too? But ... TBH ... any kind of subtractive synthesis is somehow limited, also if complexity shall not overcomplicate the instrument and increase cost.
IMO most really new sound creation methods will be rooted in the digital domain
