Situation	Recommended Action
Modern app with well-maintained gems	Safe to try globally (test in dev/test first).
Legacy code or older gems	Risky — better use the magic comment per file.
Gem development	Avoid setting it globally — you’ll affect consumers.
Rails itself	Rails 7+ core code is largely safe with frozen literals, but it doesn’t assume global freezing.
