+1 for being able to just set a config constant for the license key.
I have a shell script that uses wp cli to setup (or tear down) my development environments quickly and efficiently. ACF is one of the standard plugins I include in that process. WP Migrate DB Pro as well. DelicousBrains allows you to simply define a constant in the config file for the plugin license key. This allows me to easily add that constant via wp cli when creating the environment.

Needing to manually add the key for ACF is a step that would be nice to eliminate.
