A fairly well-demonstrated fact about COVID-19 and lockdowns is that the more severe restrictions tend to have smaller marginal benefits once enacted 
In practice, this means that the reduction in transmission for, say, limiting travel to 5km radius is probably quite small once you've already implemented other interventions such as stay-at-home orders
In other words, when we talk about 'hard' vs other lockdowns, the language often doesn't match the evidence. There's no strong reason to believe that adding small extra limits on behavior will have a large impact on the spread of COVID-19
This is not to say that further restrictions will not do anything, but it is worth remembering that adding more restrictions on top of stay-at-home orders and the like may not actually impact infection numbers all that much
