One thing to check out: ruby-lsp gets around this by using a custom gemfile, which enhances the project with the lsp's dependencies. That means you can use the gem, with bundler, without adding anything to the "official" project gemfile.

You could probably accomplish something similar, and possibly inject some rack middleware to add the view, or even mount it as a rails engine.

> NOTE: starting with v0.7.0, it is no longer recommended to add the ruby-lsp to the bundle. The gem will generate a custom bundle in .ruby-lsp/Gemfile which is used to identify the versions of dependencies that should be used for the application (e.g.: the correct RuboCop version).
