We could, but I don't think we fundamentally need to benchmark only a single thing. pausing and resuming always have significant cost and increase noise. 10-20 vectors is most likely not nearly enough to overcome that noise, and at some point we're benchmarking how fast we can iterate through memory and not `push_back` anymore.

Also note that for trivial types `erase` and `clear` are constant time operations, since the vector just has to set a single pointer.
