Where to add "post install" customizations?

Is there any place in trellis allowing me to run “one time” post-installation commands (mainly WP-CLI to remove default themes/posts/pages, set timezine and other “standard install” stuff?

Personally I see two options:

  • Using a throw away theme from within bedrock
  • create a “post-install” task with ansible

I would like to understand what is the recommended / best way more experienced people are doing it.
