Railfans are an impatient lot. Far better to be safe than sorry! Be thorough. Be right. The stakes are incredibly high here. The careful approach to certification will (we presume) raise the odds a successful revenue rollout and relatively trouble free revenue service. We hope.

Indeed they are!

But I can agree with your post as a whole. Hopefully we will see them soon in service!
