In practice, CrowdStrike very likely tests Falcon on various hardware as parts of their tests before shipping updates on it, as it’s used by a huge amount of enterprises; and a fuckup like that would mess the trust they’ve built with those enterprises.

Welp, they’re a good example of what happens if they don’t do proper testing.
