Decision on rubocop ClassLength

[trichoplax]

Currently, .rubocop.yml has the following setting:

Metrics/ClassLength:
  Max: 350

We already had exceptions to this for the classes PostsController and UsersController. A few months ago I added what I intended to be a temporary exception to this for CommentsController. I was expecting to remove it after a later pull request that would remove a method that is no longer needed. However, changes since then mean that even with that method removed the class is still over the length limit. I suspect that future changes to CommentsController will bring it back under the limit, but that still leaves 2 classes with exceptions to the rule.

How should we proceed?

• Increase the limit?
• Reduce the size of the classes that are over the limit?
• Both (slightly increase the limit and reduce the classes to match it)?
• Continue with the current limit and disable the rubocop check for some classes?
