My plan was to merge them, but before doing work that might not be necessary, I wanted to see if I could just drop a bunch of *.json files in the folder and have them added.
I might be totally unique, but it would seem like it would be nice to have a deploy/config folder where you could just dump a bunch of JSON files and have them merged. Have them processed in alphabetically order, so you could name your templates like 00-XX, 01-YY, etc to have them deployed in a specific order.
