Yes, especially in cases where significant infrastructural investment has been required of a national or local governmental regime to render the venue viable: The Senior Open and Wales is a course in point.
The discussion on Open venues is emphatically not just a conversation between the R&A and the host club, although I had always understood from friends involved that it was precisely the lack of a largescale host club at Turnberry, and thus a committed volunteer force, that made its regular inclusion on the Open rota problematic (even prior to the Trump acquisition). This problem doesn't apply to the same extent at other 'public' venues like Carnoustie or indeed TOC the itself, although Carnoustie's very sporadic usage historically (1931, 1953, 1975, 1999 in the last century) did suggest that there were indeed significant local logistic challenges, certainly until recently.
