Before we start considering performance trade-offs,
do we even have a benchmark where time spent in HashWithIndifferentAccess is significant for a Rails app?

Feature #17472: HashWithIndifferentAccess like Hash extension
https://bugs.ruby-lang.org/issues/17472#change-89602

* Author: naruse (Yui NARUSE)
* Status: Open
* Priority: Normal
* Target version: 3.1
----------------------------------------
Rails has [ActiveSupport::HashWithIndifferentAccess](https://api.rubyonrails.org/classes/ActiveSupport/HashWithIndifferentAccess.html), which is widely used in Rails to handle Request, Session, ActionView's form construction, ActiveRecord's DB communication, and so on. It receives String or Symbol and normalize them to fetch the value. But it is implemented with Ruby. If we provide C implementation of that, Rails will gain the performance improvement.
