• Many platform-specific gems aren't compiled for Ruby 4 yet, which triggers a Bundler bug wherein it selects a chooses an imcompatible platform-specific gem rather than falling back to the ruby platform and compiling. Fix: Fall back to ruby platform gem when precompiled variant is incompatible ruby/rubygems#9211

The comment has a minor grammatical issue. It should read "removed from Ruby 4.0 stdlib" (with "from" added) for clarity.
