It does appear that the site linked to by the OP auto-compiles binaries every time there's a new contrib. The Electrum master includes a .cirrus.yml file, which defines the docker container that builds the binaries. You learn something new everyday.
Nevertheless, the skeptical cynic in me prefers to build the binaries myself.
