I'm absolutely not denying that RE2 is great. Not in the slightest. I even agree with their idea to switch towards it or the Rust one.

Changing anything brings an element of risk, and changing quickly to it, even more so, which is essentially what they're proposing doing. That's where my concern lies.

Their current approach clearly has issues, but it has been running in production for several years now and those issues are fully understood, engineers know how to debug them, and there's a lot of institutional knowledge around covering them. They've put a series of protective measures in place following the incident that takes out one of the more significant risks. That gives them breathing space to evaluate and verify their options, carry out smaller scale experiments, train up engineers across the company around any relevant changes etc. There is no reason to go _fast_
