It saves me from the implementation details, this way I don't need to wear another engineer/sysadmin hat. I think the website content is more important than the SSL implementation!
Indeed! It's how security should work, and should be the default dual-goal of any piece of security software: provide as much security as possible to as many people as possible.
Having people do things without understanding what exactly they are doing is a good way to create a website with a very good ssl certificate and their private key available on the website itself… or similar issues.
