What questions do you feel should be asked? Lets Encrypt asks one question without you having to deal with it - the question where you prove you own the domain by placing a file in the webroot. This is just as much proof as the email verification you get from existing strategies. Except it involves less headache, because you aren't ordering from namecheap, then getting emails from @comodossl.com that fail SPF checks asking you to click links.
