EC isn’t widely supported on older systems, especially in enterprises: https://support.globalsign.com/customer/en/portal/articles/1...

Yes, it’d be a smaller payload and less CPU to use EC over RSA, but EC still isn’t the least common denominator. I speculate the author is optimizing for comparability over performance which is a perfectly valid trade off to make in a blog post :)

I actually just aimed for simplicity and stuff folks might be semi-familiar with. It might be worth adding a little note that EC would be more efficient all around.
