I run Apache httpd, and there's no way I'd let a wizard anywhere near my configuration files or private keys, much less run it on a production server.
I think it's about time for a free CA that is recognized by all clients, but you still need to establish a trust chain to exchange a CSR for a signed certificate. This service needs to be server agnostic. The barrier to adoption isn't configuration, and HTTPS isn't the only thing that uses certificates.
There are lots of different barriers to adoption. With this project we are attacking several of them at the outset, including the cost of obtaining a certificate, and the inconvenience or difficulty of obtaining and installing it for users who don't do that every day.
Because of the open protocol we also aspire to support users with more complex configurations and requirements, who are absolutely welcome and encouraged to write their own implementations of the protocol and integrate with their own existing certificate management and configuration methods. If you think of other barriers to adoption that we can help with, please let us know and we'll try to address them; if you just want our certs for free, please get them and enjoy!
My concern is that your reach is too far. Asking domain administrators to trust your software to manipulate private keys (and server configurations) is as troubling as asking end users to click past security warnings. The whole purpose of the CSR is to obtain the signed certificate without putting the private key at risk. This decoupling isolates the challenge of identity verification in a reasonable place (nobody is saying it's easy). With your client, you're essentially telling people you accept checks or credit cards, but only if they show you their gold. It sets a bad precedent.
I do want your certs for free! But I also want/need to trust you and know that you're following best practices, not just with me but with everyone.
Oh, our software does NOT send the private key to the CA. Never never never never. The point of having it manage the keys is not to give us access to them, it's to be convenient for the end-user, on the end-user's own system, under the end-user's control.
You can tell because our software is open source, written in Python.

We expect the users to get this software from their operating system repos, like from the Debian package repository -- the very same place they get their Apache or Nginx packages. We are not asking people to get the software directly from us, or to use it without being able to read it and check that it's safe and does what they want.
Edit: And if you want to implement your own client, we encourage you to do that -- the more clients the merrier!
