The 7th at Shinnecock is Flynn. The tee was moved slightly left and though the green is on nearly the exact footprint of the Macdonald green, it was raised and rebuilt by Flynn. Holes 1 (except the elevation change on the tee shot),2,3,4,5,6,7,8,16 and 17 are all on featureless land. Flynn didn't need to use templates (though the 7th is conceptually reminiscent of the 7th at Philadelphia Country Club and 3rd at Huntingdon Valley).
The less dynamic the ground, the more Flynn used bunkers and green slopes to provide interest and influence strategy.
In general, I find templates to indicate a lack of creativity and an artificial device lacking a natural appearance. Fun to play but aesthetically unappealing.
