I agree. If the maintainer is here, you can use certbot to add HTTPS easily on your existing Apache 2/Debian stack. If you're on Stretch or Buster the official instructions are the same: https://certbot.eff.org/lets-encrypt/debianstretch-apache

One note: I hate snaps and don't use them personally, but it would make it very easy for you to add HTTPS without changing your existing stack.
