I’ve never seen it used for backtests personally. Generally backtested results are saved as a batch of variants following some naming convention as different symbols.
You would use some convention for naming and parametrising backtests, 'different' backtests would get stored separately. But once you start updating backtests, running them in a loop with changing data, that's when the time-travel feature starts to be useful.
