ruby '2.4.1'

While this works for bundle exec rails new destination, since that includes a gem.comment (# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'), if you do bundle exec rails new destination --dev with your change, there's no empty line at all after ruby '2.4.1'. Can you instead remove the empty line following <% if gem.comment -%>? It then gives a single blank line in both cases.

[y-yagi]

The empty line following <% if gem.comment -%> is required when commenting in a loop.
If there is no empty line, the comment will collapse as shown below.

# Use sqlite3 as the database for Active Record
gem 'sqlite3'# Use Puma as the app server
gem 'puma', '~> 3.7'# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'# See https://github.com/rails/execjs#readme for more supported runtimes

So, instead of remove this emptyline, I fixed by adding a empty line to the beginning.

I kinda like it with the extra newline to separate the setup and the raw gems/groups below.

What I'd want here is one newline before the ruby statement though.

A Gemfile is still ruby, and rails coding style disallows more than one empty line in a row. I agree with the change.

Looks good. I added.
