Is it possible to preinstall Fastlane on Circleci Android Docker Images on your side? I am sure there are some small percentage of people who are not going to use Fastlane on Android Docker, but most people coming to Circiel CI are trying to do CI/CD. Having Fastlane preinstalled make it easy for everyone.

Bitrise (your hosted mobile ci platform competitor ) has already been doing this.
