Depend on railties and sprockets-rails gems instead of rails gem

[deepj]

Hello,
In my Rails app I don't use the whole Rails default stack. I do not have any purpose for ActionMailbox or ActionText inthe application. I still would like to custom my Rails stack with new jsbundling-rails gem without forcing me to install these two gems via rails gem dependencies.

I think jsbundling-rails would only depend on railties and sprockets-rails gems which are only two major dependencies for it.

Just for curiosity, how I define my custom Rails stack in Gemfile:

rails_version = '6.1.4.1'

# Custom Rails stack
gem 'railties',      rails_version
gem 'activerecord',  rails_version
gem 'actionpack',    rails_version
gem 'activestorage', rails_version
gem 'actioncable',   rails_version
gem 'actionmailer',  rails_version
