If there's a hard cut-off, that means that partially completed transactions are not included in the total. That produces less correct results than the current scheme.
With the current behavior, worrying about partial amounts being ignored isn't a problem. But there is the potential problem you report, which is mainly a risk when pgbench is combined with a badly setup environment.
It's hard to justify making a change that will produce less accurate results in the vast majority of cases, just to improve behavior in a situation where useless results are coming out no matter what.
