Ability to combine HTTP and DNS challenges in a single certificate?

[catharsis71]

Currently it's impossible to do something like this:

certbot certonly --dry-run --dns-cloudflare -d example.com --apache -d example.net

There are legitimate scenarios where only DNS authentication can be used for example.com, and only HTTP authentication can be used for example.net, but a person would still prefer to create a single certificate for both rather than two certificates.

[acme.sh can do this](certbot certonly --dry-run --dns-cloudflare -d example.com --apache -d example.net) and possibly other ACME clients

is there any possibility of adding this feature to certbot?
