It will probably integrated into Apache and Nginx, where a common
"proof" will be control of port 443 on the machine.

However, for port 25, proofs are more complicated, and there's a
strong possibility of automated cert/key rotation breaking DANE.
So the distribution maintainers need to exercise great care, and
explicit integration with the MTA/MSA may be necessary.
