The point is doing some guerilla marketing for your app, I get that. As long as people have an officially supported option to download and install software by themselves, the AppStore's convenience and security outbalance its drawbacks. It should be improved, not shut down like you want. In general, Apple seem strike a good balance between security (gatekeeper, sip, AppStore) and freedom (one can turn the above off and install whatever they want).
