Many engines that are not reusable can be started multiple times. Actually having the certification that you can relaunch with the engine after you have done a reentry and landing is required.

That's a pretty convenient goalpost to move to. Raptor also is only theoretically reusable by that metric.

it's not goalpost shifting at all.

BO doesn't have a reusable engine until they demonstrate that their engine is reusable.
