I've asked the same question of myself before, and to me the problems in finding modern template holes are twofold:
1. Many great modern holes are versions of, variations of, or inspired by the classic templates.
2. Many great modern holes are built on unique sites with distinct landforms that couldn't be replicated without significant, unnatural-looking earthmoving. This is especially so because the minimalists responsible for this Golden Age focus on using what the land gives them. Of course, someone could replicate such features if they wanted to, but I'd bet much of the effect would be lost in unnatural settings. There's a reason most template courses (the Bear's Best kind, not the Raynor kind) are utter bores.
There are probably exceptions out there. I just struggle to find them.
