Indeed you are - you're missing to update a lot of vec_safe_grow[_cleared]
calls.  Esp. the lto-streamer ones warrant a , true arg since we explicitly
streamed the number of elements.

How did you select the ones you updated and those you did not? (which
is why I asked for a boiler-plate replacement of , true first, then making
the parameter defaulted to false and adjusting those cases you found)
