Yes but when you have to do this 13 times, it gets really annoying to manage all those API keys. Especially if you need them in different processing contexts. If I could just have a single public/private key pair for my app it would simplify managing all the extra services I use.
Thank you! I suppose yes, that it would amortize a few steps. (But as I mention in another comment, that only amortizes the management of the secret portions, which is a small portion of the objected to "insanity".)
